Which ones are correct or most recommended depending on the situation and why yould do it like that.

 

 

For the first i don't think i would ever use the second fingering and you will never see it in any official DLC as far as i can remember.

 

For the second ones it will really depends on what's around. The first one means that you'll probably need to reach something with the 3rd of 4th finger on another strings while the second ones is more likely to add the 1st finger somewhere on a lower fret.

 

As for the last that's the kind of situation where you either gonna move to a power chord kind of shape or simply do another barre quickly like in that kind of situation :

Overall it's mostly what is around that will make one fingering makes more sense than another.
