Party 1/2 Preflop Questions

[MisterNatural]

I've been reading lot of similar posts, but most of them are geared more towards 5/10 where raises are apparently more effective. Assume the room is a typical Party 1/2 with the biggest pot size. No matter who is raising, there are usually 4 players seeing the flop. Both blinds are usually in and rarely raise unless it's a AA-JJ or AK. There is no buying the button, getting it heads up, or blind stealing. You will be called down with just about anything by two players except as noted. Thanks!

Call, Raise or Fold?
1. Everyone limps to SB with Q7s
2. 4 limp to SB with KTo
3. 1 limp to the SB with A5o
4. UTG limps to UTG+1 with A5s (it's 50% that someone will raise behind)
5. Folded to SB with J6o
6. UTG limps to SB with QTo
7. UTG folds to UTG+1 with ATo
8. UTG limps, UTG+1 raises to CO with 77
9. Folded to Button with QJo (both blinds will call)
10. Button bet to SB with K9s (BB will call even if you raise)
11. UTG with KJo
12. UTG limps to UTG+1 with KJo
13. Folded to CO with KTo (button and blinds will call a bet)
14. 1 limp, Button raises to BB with KTo
