Can move 3 gallons of wine from the primary fermenter and rack it into a 5 gallon carboy and be ok or do i need a 3 gallon carboy

It'll fit, obviously, but I wouldn't leave it there long. Oxidation could easily be an issue, if most of the fermenting is over.

Not a good plan. You need to eliminate all the headspace up to the neck in the carboy. It wouldn’t take long for the wine to spoil.
