Er, whatever that happens doesn't matter. As for Waver being part of the Reality Marble, yes well the novels certainly hint otherwise (aka he likely is). Ioian Hetairoi itself is built on a pipe dream, an impossibility shared by them.

Spoiler for Rider's farewell:

Waver hung his head, and did not raise it. Alexander took that as consent. There was no need for words. From this day until the end of time, the servant would be guided by the figure of the King, and the servant would remain loyal to that memory. In the face of the oath, even separation was meaningless; under the command of Alexander, the bond formed between King and servant was eternal and beyond time.

Spoiler for Waver's realization:

The battle was only for him. No one had noticed what he had surpassed by himself in his loneliness. No one was praising him.

But if one were to call it a cruel treatment - then no, it wasn't.

He had been rewarded with more than enough words of praise just now. The grandest King in the world had recognized and assigned him. He was told that he would be added into the ranks of the servants.

The order of events was simply reversed.

He had now been praised for the far future as well; the only thing to do now was to devote all that remained of his life to accumulate enough accomplishments to match that eulogy.

Yes. Simply because of those words at that point in time - he was not alone.

Does that mean we'll see his servant version? Doubtful, unless is a side material or something.

I don't think he's in the Throne of the Heroes, but he would be in the RM somehow, or Gen 'LOLGRIMDARKUNHAPPYENDINGS' Urobuchi wouldn't have bothered to put those lines. Plus, I doubt that Rider can summon from the Throne of the Heroes guys lol. He's not a Caster. Furthermore, none of those heroes have Noble Phantasms. Remember that Kojiro was also a Servant even if he didn't exist and was really a ghost playing the role (and like these dudes didn't have a NP). The word isn't as exclusive as you think it is.
