Sort of building off Windi_1's post (which I only saw half way through writing this)

The Star of David is a symbol of Judaism.

I think this one is based off of Sufganiyot! For Hanukkah, we eat fried food, to celebrate the oil that lasted 8 nights. One of those fried food is Sufganiyot, which is basically a jelly filled donut!

This guy seems to be based off gelt! I don't remember the history of the custom off the top of my head, but gelt are chocolate coins wrapped in gold foil! You can often use them to play dreidel with!

This guy's based off a dreidel or sevivon, a spinning top, with letters on each side standing for "A Great Miracle Happened There/Here." At one point in our history, when Jews were oppressed, it was forbidden to learn Torah. So, children would learn it in hiding. If a Greek patrol came by, the children would pull out these dreidels, and pretend to be playing a game. And today, there is a game you can play with them!

Maybe wrapping paper? I'm not completely sure, but we typically give out gifts for each night of Hanukkah!

Perhaps this design is based off latkes, which are basically like hashbrowns. Fried grated potatoes eaten with applesauce and sour creme.

Oil lamp, is what Windi_1 wrote, and that seems completely plausible!

This guy seems to be based off the Menorah, itself!
