German? emergency coins/ local coins [επιλυμένο]

I recently bought theses coins, I'm not entirely sure what they are but they were listed as emergency coinage, I don't have a ruler, but the white coin is similar in size to a US Eisenhower dollar, while the reset is most similar in size to a US quarter. I think the white coin is made of porcelain (same with the brown coin) but I'm not entirely sure about the composition of the other two coins. I do not have a scale so I cannot list the weight. if the pictures aren't clear enough, I can send more.

They all have Latin script so they should be easily searchable. Turn off all category filters (if you use any) and put in a couple of words you see and you most likely will find them.

Greetings.  I believe that this is the 2nd one  (on the Top right).

The remaining bottom 2 look like tokens or medals.
