My thoughts..

1; I think this is fine if I saw Villain 3-bet with AQ and/or saw him bluffing a lot. I didn't so turn is a c/f (although 6 outs makes it closer).

2; This should have been an easy turn c/f. I get minraised in a 4-way pot by a passive donkey and still manage to get stacked with one pair. wtf.

3; His small raise didn't seem like a draw, but AK/KQ(?) is too likely to fold. Should've pushed..
