Hand 1 is a standard call at this level probably. He either has a set, TPTK, TPGK or flush draw. How was villian playing in previous hands? This is how you can tell what he mostly has.

Hand 2 - Played fine, cbet turn, c/f river

AQ in 6 max is always a raise for me in whatever position. Be careful with reraising it though because you may run into AK. I typically will reraise though with position against the weaker players.
