Discuss a couple of hands. Live 200NL ($1/$2 NL)

Hand 1
=====
Late position
There is a $15 bet before it gets to me by Aggro-loose V1.
I decided to fold.
Is this a terrible EV- play?
(Flop comes K 5 2 and V2 bets $15. Glad I folded!)

The next hand, I get 33 again.
V1 bets $25, and I fold again.
(Flop comes K 7 8 Glad I foldedd)


Hand 2
=====
I get K9 when OTB.
Is this worth limping in hopes to hit K and have it check to you?
Or would you only raise for hopes of a C-bet?
Or just fold?
What if V bets $10 before you?
How would this change?


Hand 3
=====
200NL live table.
I get KJ in MP.
V1 bets $6 and I fold.
Is this being too nitty?
After I fold, V2 bets $40
[SPOIL]Flop comes A Q 7
V2 bets $60
Glad I folded.[/SPOIL]

Hand 4
=====
200NL live table.
KJ suited in EP.
V1 bets $12 and I folded.
Is this a terrible play?
Would you fold KJ suited in EP ?

Hand 4
=====
200NL live table.
KJ suited in EP.
V1 bets $12 and I folded.
Is this a terrible play?
Would you fold KJ suited in EP ?

I would consider play this hand, because it was live, unless that 12 bux betting player is super nit.
online, I am not sure, depends on player.
