should i have folded any of these shoved hands?

craigcu12

hand1 the reason i raised to 12p here was because i will raise with hands like J10o Axs and 77 in pos, so if i did a 20p bet it would be easier to know that this is a stronger hand.

hand2 is their any unpaired hands apart from AKs,o that are strong enough to still call a shove preflop before i know for sure if the villian is a maniac.

hand 3 it might have been yesterday but this time it was JJ i had, i decided to make the call after what people were saying about my QQ and right away started hoping for the A and K to start away thankfully i hit the set but he got the straight on the river so i lost.
is QQ the last of the shoves or can i do it with JJ at this level too?

First 2 you should have folded, the last one would be player dependent (is this guy going all in with worse than JJ, I would have probably called the all in here so I don't mind the last one)

I think if you are worried about what cards to shove pre or call an all in pre then stick to some basic rules

AA

KK

QQ

AK suited

Anything else consider the player you're up against, I start thinking about folding with anything less than these hands if I'm faced by someone shoving all in pre, especially if i know the opponent to be quite tight.

Consider your opponents stack as well, in the last hand your opponent had 1/4 of a buy in and that's why I would be more likely to call with JJ here. It's one of those 'well, even if he's got me beat I'm not going to lose much' situations.
