If my carrier is holding one of my fighters and one ally unit does this one move rule apply to the other allies fighter as well?
Yes.
Any defending fighter that loses its carrier (even if an ally’s) gets 1 movement to land safely. It does not matter that there are multi-national fighters on the same carrier. But if some but not all of them can land safely and 2 or more players are controlling the defending fighters, then you will have to agree on which ones are lost and which are saved!
