Coin 1 isn't Chinese. Not sure what it is, but it has a bust on one side. Coin 2 is not a coin but a token. Probably Japanese. I know that's not much help but it's a start
Is the first one 29 mm, about 6-7g? It looks like a heavily damaged RoC 10 cash, but it's hard to tell at this point. If so, it has almost no value in that condition. Second coin says "天山閣" tian1shan1ge2 Tianshan is a mountain range in Xinjiang. 閣 means pavillion It appears to be the name of a yakiniku restaurant in Japan. It may mean other things as well, but #2 doesn't look like a circulation coin.
Regarding the 1st coin, I agree with @The Eidolon It's a Chinese 10 cash. I think the top pic is the dragon. There are numerous types, and if I remember correctly, many are common. Here is one for reference
Nice attribution. I thought I saw a line of Arabic across the reverse, but was fooled by what I thought were Chinese characters above. So I was looking for colonials like French Indochina or Netherlands East Indies, and nothing matched. Once I knew it was only 24 mm, I knew my initial guess of a 10 cash must have been wrong, as those should be 28~29 mm. The wreath originally made me think a Republic of China minted 10 cash, but the RoC 10 cash have very different wreaths. Thanks for resolving the mystery.
