'My Plumeria is growing crooked in the pot anyone have any suggestions on how to fix that? '

You can either repot it more upright or stake it somehow.

'Also does this inflo look ok? '

If that is an inflo, it looks like it is ready to fall off. Def. not alive.

' I had to actually cut off some black rot last night all the way down to the joint '

I don't see anything cut off in your pictures. And that seems like an extreme measure to take. You might have to explain.
