Ranges for standard situations #1

[mattiesmat]

I would like to know what ranges you guys have in different standard situations and how mine are.
The idea of this topic is: I give some situations and anyone interested posts their ranges and comments on the ranges of the poster above.
This way I and others can imrpove and learn about making better decisions in those spots.
I am aware that I give away reads now, but I think improving my ranges makes up for those spots where this will be exploited.

Situation:
a = only unknowns players left to act
b = only solid winning multitable regulars left to act
c = only LAGG donks left to act

1) 1st level (BB=20) folded to you in CO.
2) 1st level (BB=20) folded to you on button.
3) 1st level (BB=20) folded to you in SB.
4) 1st level (BB=20) 2 limpers, you are in SB.

1b) AT+, 99+
1c) AJs+, TT+

2a) ATs+, 99+
