Get hold of an historical atlas. Basically Turkey lost nearly all of its holdings in Europe and new countries were created e.g. Yugoslavia. Germany lost parts of France.

Enemies in WW1 - you forgot Austria-Hungary, Bolshevik Russia and the Red Army.
Enemies in WW2 - you forgot Italy and Vichy France.

Territories gained in WW1 - Turkey made minor gains along the Black Sea. Germany lost pretty much everything as a result of the Treaty of Versailles. The Bolshevik Party of Russia and the Red Army gained control over all of Russia, as well as the Ukraine (which eventually led to the creation of the Union of Soviet Socialist Republics.)

Territories gained in WW2 - Absolutely none. Germany lost it's Independence, as did Japan. Italy also lost their's to a minor extent.
