Can you identify these coins? [solved]

I recently bought a collection of coins and exonumia and I need help identifying these four. The collection included coins from Spain in the 1870-80s, United Kingdom farthings 1939-1954, coins from Taiwan, Japan, and China, and United States tax tokens.

The first one I think is some sort of token. I had a token in the same collection that I bought that was a game token from the United States. It has some strange text on it that I can't tell if it is part of the token or not. It reads CASH OR TRADE VALUE — TOKEN ---. On the other side there is more text reading TOKEN AW-  FOR SKILL. There is also a large R in the middle on both sides. It is around 20 mm diameter and weighs 4.440 g.

The second one I am not sure. The outline of the bust is visible along with the letters -CA and D- and I can't quite read the date. The reverse I can't read anything. It's diameter is around 19 mm and it weighs 2.591 g.

The third one I can't read anything but on the obverse I can see a bit of the bust and on the reverse some sort of Eagle or bird. It's diameter is around 25 mm and it weighs 4.344 g.

This one the closest one I could find was this one but the symbol on the top is different. I believe it is the same denomination of coin from the Empire of China but not sure. It's diameter is around 17 mm and it weighs 1.068 g.

N#22475

Any information you can share would be much appreciated. I have been researching these for hours now and haven't found any other information.

2. Guessing the CA is the end of REPUBLICA lettering. 

Coin #2: N#10162

Coin #4: N#35119

3. Maybe France 

N#485 

N#486

 Yes, that later reply gave REPUBLICA DE COLOMBIA lettering - 

'the reverse I can't read anything' does actually show the II letters 

for the 2 Centavos. Still not sure of the date, maybe 1921 perhaps? 

The imprint on the first coin is pretty much the same as this token: N#316230

There is also another set of marks on both sides: PP.

 

 Agreed - same imprint. I made this > 

THIS TOKEN HAS NO CASH OR TRADE VALUE // THIS TOKEN AWARDED FOR SKILL 

Thanks so much everyone. This has been super helpful.
