The K9 has some showdown value and good high-pair strength so it is at least marginally profitable here (If you're trying to control variance, consider a fold). KQ is obviously a preflop cap against a nut.

The first hand: I'd peel one, and fold the turn. I am beat by ace-high, any joke pair, and some straight cards.
(3,4,5,6,7,A + any PP + stuff that can draw out on you like 98). However, I need to check the math on this.

The second hand: Call the flop and turn for combined reasons of drawing and likelihood of being ahead. Once you're in for 7 SB, you don't have to have 50% equity to continue.
River is an easy call: only things that beat you are AA-TT, Ax, Jx, Tx, 33.
