Not a lot of hands on this villain. Doesn't seem a total donkey or calling station or maniac.

Hero ..?

Should I bet here? I can't see many hands calling here that I beat. Or would a FD call this turn often enough? Or maybe even a J?
Is this an easy turnbet?

I would bet $8 here. There is no definite indication that he has a Q. If he calls I c/f the river. If he raises I think you need to fold.
