Need help with Chinese coins

Hi, please help me to ID coins. What only I know is that they are Chinese. But what year? And who is ruler?
1 coin:
2 coin:
3 coin:
4 coin (I think it is Japanese):  

Thank you in advance!

The first one's not real.

Or maybe I can't find it in the catalogue. If it is real, it's worth a lot of money. On the reverse it says "Boo-ciowan, equals 1000 (cash)" and on the obverse it says "Yung-chen yuan bao."

Thank you for help  Kemlo and SmartOneKg
