A few overpair hands

Party is sooo fishy. I just finished whoring Riverbelle and I rarely was able to stack with an overpair. At Party, it seems to happen all the time.

Hand 1
Villian is 37/7/2. Obviously could be AA, but is this JJ, QQ, AK enough to make this call? Large preflop reraise had me suspicious.

Hand 2
Villan was 48/11/1. I was kinda on tilt from just losing AA vs KK, so when I saw the river ace I decided to rep it and put her all in. Spewage, right?

Hand 3
Villian is 41/1/1. Decided to rep the turn ace, should I fold the flop? I always worried that flop minraises mean monsters building pots, but now I'm finding thats only the case in a multiway pot. HU, these min raises dont seem to mean much. Whats the standard response to the flop min raise?

Hand 2: I like a turn re-raise all-in. I think that turn bet tips his hand way too often.
