I used to think Yuki's smile keeping the group together are BS. But without her randomness and optimistic, the group would be always uptight and stressed all the time. In the manga Kurumi, Miki and Yuuri are shown to argue and fight more often.
Even Yuuri and Yuki argue a bit at some point. In the Manga they show how the beach day/games played with Miki help keep morale, else the same thing that happened with the College group would happen where they drive each other apart
Her voice actor literally has the BEST laugh ever. If you don't believe me go to episode 4 and watch the first few minutes before the op, you'll catch it.

Yes, she was aware of the apocalypse at the very beginning of it (like when Kurumi killed her zombified crush), so it’s highly likely she knew about the whole thing but wasn’t aware of it cuz crazy.
Yes she is but she chose to reject it and stay being happy, without her, the group won't survive because being trap in a school with limited supplies can give you depression
