fwiw, cuz I'm far far from an expert ...

(1) I fold these oop.

(2) I raise first in, raise 1 limper, usually limp after 2 limpers unless I am pretty sure one is weak and will fold to a pfr. I don't want to play a raised pot against 2 or more players very often. I call a smallish raise if they are deep enough to make it worthwhile to try to catch.
