The first token is of the Peter-Paul Castle in St Petersburg, Russia. That castle is the building on the left in the token. Then the Bronze Horseman is the other significant part of the token. Commissioned by Katherine II (the Great) to Peter I (Peter the Great).
The second token is also St Petersburg, Russia. There is the sphinx because there are a number of sphinxes on the banks of the Neva River in St Petersburg. Then I would guess that the building with multiple spires is 'Hram Spas na Krovy' or 'Church of Savior on Blood'. That being the very iconic Russian Orthodox cathedral in St Petersburg.
Token 3 is the Bronze Horseman again from St Petersburg Russia. Written on top is "city of white nights." Then below is "and water bridges."
The 4th token (which is on the second row) is this guy. On top it says St Petersburg. On bottom it says the guys name which is Auguste de Montferrand. He was the primary architect for St Isaac's Cathedral in St Petersburg and for the nearby Alexander Column.
The 5th token is St Isaac's Cathedral itself. On top it says what is on the bottom which is Saint Isaac's cathedral.
The 6th token is the other side of the third token. As you might be able to tell it is another depiction of Saint Isaac's cathedral. Then on top it says "City of White Nights" and on bottom "and water bridges."
The 7th and 8th tokens are the same tokens. Just different sides. I got the tokens at The Museum State Museum of Fine Arts which is in Moscow. The token celebrated 100 years of the museum in 2012. I don't know who Edgar Degas was. But according to wikipedia he was a French Artist. It might have been that he had some pieces of art in the Museum. I don't remember.
The last token is a metro token. It was good for one fare on the metro in St Petersburg. In Moscow cards were used instead.
