Help needed with Chinese coins

Dear friends, I cannot make out what these coins are. The search on the numista site has not yielded any positive results... Maybe, they are fake... I would appreciate any help. Thank you very much in advance! Best regards, Dmitri.

The left and center coins are probably Qianlong Tong bao cash. The coin on the right could be a cash coin from Japan or Korea.
