Slightly inept preflop questions I SHOULD know the answers too.

[Alex/Mugaaz]

Would these pot odds be enough to be EV neutral(or close enough) in the following situations? Factoring in both opponents typical hand ranges and your positional advantage/disadvantage? (SB/BB is 2/1 structure)

1: 5To in BB vs UTG raise and 8 callers.
2: 35o in BB vs MP1 raise and 3 callers.
3: J7o in SB vs UTG limper, MP1 raise, and 2 callers.
4: Q3o in SB vs UTG+2 limper and 3 callers.
5: 58s on the button vs UTG limp, UTG1 raise, and 3 callers.
6: 2Ts in the CO vs UTG+2 limp, and 3 callers.
