Help with questions?

I don’t know if this is in the right place but I hope it is.

Anyways, I have a problem. I’m working on a story and I want to have the MC ask some questions about the other MC. I already have questions like: do you have any family, how old are you, where are you originally from. My problem is I want the reader to know a bit more about the MC but I don’t know what other questions I should put ?

Can anyone help me with some questions!
