hand 2 looks tough...lots of turns will look bad, but I'd discount a flush hurting you because he only min raised a board he shouldn't expect u to fold to that.
looks more like KJ, str8, worse 2pr, slow played TT-AA (maybe an uberdonkish top pair). I guess bet the turn 1/2 to 2/3 pot, or call a bet from him, and fold if he tries to get all in. maybe it's weak, but u have no reads.
