Answer 1

Do I answer here or there? ;)

They are all fine. I think #5 would be better with "hubo" instead of "habia" though. If I understand correctly, you would be saying that there was a dinner at the house, and in this case "hubo" just sounds better to my ear, but they're pretty interchangeable if you ask me.

Hope that helps!
