5 Centimeters Per Second is the only one that didn't and like Kanon said it was more bittersweet than a downer.

And ...

Spoiler:

Voices of a Distant Star: No, she didn't come back. She was young in space going farther and farther away and the guy was on Earth gradually getting older. Not too many people are going to be dating a guy as old as their grandfather by the time they come back.

5 cm/s: The guy moved on. Not very uplifting.

Beyond the Clouds..: Left for you to interpret whether or not the girl died.

She and Her Cat: Owner broke up with her boyfriend.

Relationships don't seem to have "happy" outcomes his titles.
