I think you way overestimate the likelihood of the villian bluffing given the strentgh you've shown is (almost) all hands.

Hand 1) Fold: You're substantial reraise represents a slowplayed AA/AK ATd or two pair+. Also, UTG cold called a raise and a big reraise and then pushed when the flush hit. Unless you know UTG is a maniac, I fold knowing I'm beat.

Hand 2) Fold. You only beat a bluff. It looks like AT/TT to me. Espcially since villian can't have TP and be on a draw (you have the Ah)

Hand 3) Call. In order for villian to have you beat, he has to to have a flush or a boat. If he has a flush, he hit it on the turn and would have reraised you there. Unless he has KQs, he has to be worried that you have something like KQ/KTs and would push over him on the turn. If he has a boat he'd have to have a set on the turn (and he'd reraise you with AA/KK/JJ) or A4. The only hand that has you beat and makes sense is A4 (where he hit his miracle card and wants to get paid accordingly). His bet looks like it's designed to make you fold which would imply a hand you beat.

Hand 4: Tough. Very tough. Especially b/c the board is so dry. I wan't to call, but can't imagine a hand I beat doing this. On the other hand, and hand that beats TPTK, would want you to call. I'll say, other than hand 3, it's the closest one to calling, but I'd have to let my time run out and fold. So tough.

Hand 5: You are beat. Fold. UTG as 2 pair + (likely a set or a straight). He's reraised you twice and you've only shown strentgh.
