Calling Raises

Under what circumstance do you call raises.

I am not talking about 3-betting -- I will 3 bet with QQ+ AK+ and other hands under different circumstances

Assume full stacks

For example standard TAG raises from Mid Position --
No other callers
I have position
I call with any pair , AQs

Now what if there is another caller before you act.
TAG raises from early to mid position.
Another TAG/sTAG calls
I have position
what do you call with?

What if there are two callers?

What do you do from the blinds?

vs one solid player at six max: i call with 22-99, usually threebet TT+, AQ+, muck everything else.

vs one solid player at full ring: i call with 22-QQ, threebet KK+ AK AQs

vs one solid raise + call: i call with 22-TT, most middle suited connectors, KQ, KJs, and other decent multiway pot hands.

on blinds: i usually only call with small pairs and occasionally a hand like JTs or something, every thing else im threebetting or folding (KQ, AK, AQ, AJs, 99+, maybe pairs even smaller if the raiser is in late position and has been getting out of line)
