Answer

There is nothing wrong in Islam with accepting presents from non Muslims or giving gifts to them during the Christmas festival, as they are not religious acts in themselves, but social customs.

However, one should make the intention when accepting or giving the gifts of bringing them closer to Islam and you give or accept something which is not associated with Christmas like crackers etc… (See Fatawa Mahmoodiyah p.174 v.18 & Aapke Masaail p.67 v.1)

Only Allah Knows Best
