Okay, using a technique to let AGTH translate the text (sure took some work but I got it), I have some idea of Silfa's story.

Spoiler:

It appears that Silfa is a defective robot - very emotional, rebellious, and dishonest, and was slated to being dismantled and scrapped by the manufacturer. She was aware of this and apparently ran away, hiding in the shipping crate that was sent to Takaaki. In fact when Takaaki was about to call the manufacturer when Silfa wasn't doing her chores right, she prevented the call and begged him not to let anyone know where she is. This also explains why she's afraid of strangers, and why she hides in her box often.

Later Ilfa talks to Takaaki about this, and it seems Ilfa is a very stern disciplinarian of a big sister towards Silfa, actually wanting to literally spank her on the butt when Silfa slapped Takaaki (who interrupted this). Then to protect Silfa and give her a chance, Ilfa gives Takaaki a "Maid Robot Authorization Card" which gives Takaaki authority to take Silfa in and train and evaulate Silfa by playing the role of a husband (hence Silfa calls Takaaki "kosujin-sama", if I got that right).

As to why she gets into catfights with her sister Milfa (aka Harumi), it's because Milfa is a better robot in terms of household chores and outdoes Silfa especially in cooking, which gives Silfa a lot of insecurity.

Also on Milfa

Spoiler:

If what I gathered is right, it should confirm the rumor from a blog I read that Milfa is a mental-transferrence (i.e. AI transferred from another system) from the automated stuffed toy bear that Sango was working on from game 1 and the anime - the same bear Takakki looked at from the underside causing it to hit him and jump back, and Ruri accuses Takaaki of being a pervert for looking at a girl's crotch. I get the feeling that that act gave the AI the idea that Takaaki took its "chastity", thus during the conversion to HMX-17b, that idea manifested itself into Milfa's clinginess to Takaaki.

A conversation with Ilfa suggests that Milfa wants to be thought of as human, which is another factor to her clingy behavior, and apparently her name Harumi Kono was given to her as a favor asked of from Ilfa so that Milfa can get close to Takaaki.

Also, Milfa's new name Harumi seems to have been derived from the Japanese pronounciation Mirufa spelled backward (Fa-ru-mi, which sounds like Ha-ru-mi).

Here's something that caught my attention
One day Milfa finds some kittens and decides to keep them in the school much to the teachers' dismay. She keeps them in the student council room, to the delight of Tamaki and Konomi. Tamaki suggests keeping them in a cage for their own safety, but Milfa objects. Much later on Tamaki rushes to Takaaki in a panic because the kittens got out when she opened the door. The four of them go on a search.
And here's the interesting part: Milfa is on the phone talking to her "onee-chan" (presumably Ilfa) and says something about Satellites, hacking, United States, and Soviet Union (??? does she intend to hack into US and Soviet Spy Satellites just to locate the lost kittens!?!?)

Also tried it on Yochi's route

Spoiler:

I might be mistaken but it seems there's a point where Yochi and Charu get into a fight and end up not seeing each other for some time (and this seems to be start of where the option to see Yochi only has Yochi's chibi form instead of the two friends together in the location menu). So one day while eating out Takaaki drags Yochi to Charu's place and forces them to make up. Neither wants to apologize to the other, so Takaaki decides to settle it with a board game (not sure what it is, but it sounds like Railroad Tycoon), and the loser will apologize to the winner. Yochi loses, but doesn't want to concede and accuses Takaaki of conspiring with Charu (who says "Good job" in english), and her lively personality really goes all out here (as in she's really loud and blabbering).

Yochi demands a second game, so Takaaki suggests a card game (highest card wins. Blackjack perhaps?). Yochi wins the first round, but begins losing each succeeding round. Apparently, Charu is good at Card Counting so is able to beat Yochi.

After a third game demanded by Yochi, she still comes out the loser, so Takaaki declares Charu the winner. Yochi finally admits defeat. Charu then states that Yochi do something as an apology. What is Yochi to do? Serve tea, in a naked apron! However, Charu changes her mind moments later. (dang it!)

Found a funny comment from Charu during the Swimming Pool trip: (note: based on Atlas translation)
"Yochi is a lonely woman who doesn't have a boyfriend to show off her bathing suit to"
This was followed by another funny comment regarding Yochi's boobs ("growing since summer", and something to do with buying a new swimsuit every year). Needless to say Yochi was pissed off.

More funnies: when Takaaki sees Haruka there, and asks what she's doing, she replies that she's dieting . (which is unnecessary for her given her current figure). Also, when Yochi addresses her as "auntie" (obaa-sama), Haruka "corrects" Yochi by insisting on being called "big sister" (onee-sama) .

Then there's the part where Yochi is pissed because of Takaaki inadvertedly staring at Haruka (you know why ). And it seems Yochi comes to the conclusion that Takaaki has an Oedipus Complex (that's the exact wording from the AGTH/Atlas translator).

Okay, this one made me LOL. 2 days after the swimming pool trip a very hungry Takaaki (who inadvertedly pissed off Silfa the previous day by walking in on her while she was dressing up, thus the robot maid refused to cook dinner and breakfast for him), bumped into Yuuji, Konomi, and Yochi. Yochi belittled Takaaki at first for his "pervertedness", then began stuttering (perhaps she was going to give him a bento). Takaaki responds (again AGTH translation) "Cock-a-doodledoo?" (the original Japanese text is コケコッコ?). Of course Yochi vehemently says "That's not it!".

Unfortunately before she can give her bento to Takaaki she's interrupted when Harumi, Nanako, Marianne, and Charu all show up offering their own Bentos (after apparently hearing the news about Takaaki not eating two meals in a row), but not before Silfa angrily shows up and shoves her own bento to Takaaki. In the end Takaaki is swamped with a mountain of Bentos, and to top it off Konomi gives her own too.

Now this takes the cake. From what I gathered in the next meeting with Yochi, she seems to be really conscious about her boobs. When Charu points out that Yochi's blouse has one undone button and that Takaaki can see her cleavage, Yochi gets into a fit and launches a rant about boob fetishes (AGTH translation for the term is "Milk Maniac", but I'm sure I have the gist of it right). Apparently Charu has no misgivings about this and encourages Takaaki to fantasize or something, much to Yochi's irritation. The conversation goes here and there and Charu says something that kind of stikes a nerve, and eventually

Spoiler:

Yochi actually decides to "give her chest" to Takaaki - or rather, let Takaaki grope her boobs! And he does, albiet hesitantly, while Yochi reacts as erotically (i.e. moans) . After a few moments of going "dame" (i.e. pleading to stop), she finally loses it and decks Takaaki enough to knock him out.

Oh boy Yochi's path is full of silly surprises. At the next meeting Yochi rants about Takaaki not making it though the "boy's rite of passage" (don't know how that came up). The really funny part was what Takaaki said as a suggestion to sum it up

Spoiler:

he says "Circumcision" (at least that's what AGTH spewed out), much to Yochi's horror.

She "corrects" him with another term

Spoiler:

she hesitantly says "skirt flipping" , causing Takaaki to do the "fall flat" reaction

Geez, continuing Yochi's path and her statements are cluttered with words that apparently scream "puberty blues". There are just too many to list so I'll hold this one for now.

Okay this isn't specific to any girl, but I snagged this screenshot during Yochi's path (a scene at the burger stand)

Spoiler:

Look closely at the staff on the left side


It's Multi and Serio!
