Answer:
Hanukkah gifts can be anything.
Some families exchange presents, and some do not. Gift giving is most common among American and Canadian Jews, but it's a custom that only started a few decades ago due to influence from Christmas.
If gifts are exchanged, they are usually given each night during the 8 nights of the holiday. There is no rule about how many presents are given each night, but it is often 1 per night.
It is more traditional to give money or chocolate coins than gifts.
