Identify, real/fake Chinese coins?

Hey! Happy Easter!

I've got 3 Chinese coins that I need help identifying:




The first two coins from the left I found while trekking Mount Rinjani in Lombok, Indonesia. I know that Hindu people from around Bali use them in rituals and offerings and that are lot of fakes also.
The third coin I received as a gift from someone that bought it from some shop/market in Shanghai.

Any chance some might be real?
Thanks!

They are all real.
