All questions depend at least on:

a) your image - if you have raised 4/5 times in the last orbit, you should pass on;
b) table image - if there are many calling station behind you, you should pass on;
c) stack sizes - if there are many shorties at the table, you should pass on.

Now closer:

1) Unless players behind you are tight and you are destroying the game - pass on;

2) Raise. Unless limpers are short. I sometimes call with one or two gappers.

3) Call a TAG. Raise a LAG like 1 in 5.

4) See 2.

5) I raise like 1 in 3. Otherwise call.
