Hand 1: You probably have too much equity to fold. Put them on ranges and check PokerStove.

Hand 2: AK-AJ is a pretty inaccurate range for a loose/passive here.

Hand 3: Check pre-flop. Your hand plays terribly and you're not in position. I'm not sure what you're asking about at any other point in the hand or why you even posted this to be honest.

Hand 4: Your pre-flop raise size is terrible, go for .12-.14 instead. A sample size on Villain's stats is useful here. For him to lead pot two streets setting up a river shove, it's hard to say how much is in his range that isn't 66 or 55, but I probably call down instead of shoving the turn since he's a passive guy taking an extremely strong line. Note flush draws are fairly unlikely because of the Ah and Kh being exposed.
