Odds are, they're probably all correct in what they're actually teaching you as good flying habits - with a few exceptions most things in flying have more than one way to do it.
Problem is they're clearly not singing from the same hymn-sheet, which is poor practice in itself when teaching an ab-initio student (which with a 14 year gap is effectively what you are). You need consistency until you're properly back in the groove again, then is the time to start using different techniques and starting to work out what you are most comfortable with (rather than what just works).
I'd suggest either having a word with all of them and politely asking for a bit more consistency, or simply arranging to try and fly exclusively with whichever instructor you feel most comfortable with.

N.B. Re: wing-down .v. crabbed, it does depend a lot upon the aeroplane. Certain aeroplanes only handle crosswinds well with wing-down (the Shadow and Tristar for example) whilst others really do need crabbed - the PA38 or G109b being two obvious ones. Some other aeroplanes will happily accept either, most of the high wing Cessnas for example. But again, I'd suggest using something that both YOU are comfortable with, AND suits the aeroplane. Don't believe the people who tell you that only one method or the other will work, it simply isn't true, except for certain types.
