Loose passive games - call or raise?

[Mano]

I often find myself in loose passive games in middle to late position with good, but not great starting hands and often question weather it is better to just limp along after several others have already limped and see what to do on the flop, or raise what may likely be the best hand. I was hoping some of you could comment on some of how you would play the following hands in middle or late position, assuming at least 2 or 3 limpers already in and loose passive blinds:

1) AJ s/o
2) AQ s/o
3) KQ s/o
4) medium pp (8-J)
5) small pp (2-7)
5) KJ s/o

If any of you would care to comment on any of these starting hands I would be interested in how you would play them. Thanks.
