Need a check up: a few hands to review

[La Brujita]

Just wanted to see what you all think of some of these hands. I will post the hands and then post what I did later. These hands are not super exotic but in a way that is the reason I am posting them if that makes any sense.

Hand 1:

4 handed $30 at Paradise. I am in the BB in second chip position with 2000 chips. UTG has 5600, UTG+1 has 1100 and SB has 1300. Blinds are 50-100. Big stack is very very aggressive and open raises to 300. Folded to you holding KK, your move?

Hand 2

Five handed at Party $30. You are the short stack with 550 chips before posting the BB of 100. Folded to the SB (you have no read) who pushes all in. You hold Jc 9c. Your move?

Hand 3

7 handed at Paradise $30. Blinds are 15-30. You have about 950 chips and hold red queens. You open raise to 90 and the button (who has you covered) flat calls. Flop comes Ts 2s 6h. You bet the pot (195) and are called. Turn is 4h. Your play and why?
