In Angel Beats, did Hinata and Yui... (Episode 10 spoilers)?

It's really left up to your interpretation. The anime was the original medium, so there's not any details that were left out in an adaptation or anything. Seeing as the major thing she wanted to do before she moved on was get married, it's possible that they really did meet, but because she died before she got a chance, she was unable to fulfill herself.

No, it didn't happen. But the implication is that it would happen in the future, once both of them had reincarnated.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
