Typically we are referring to WWII when we talk about Germany's allies, so in that case it would be Italy, Japan, Hungary, Romania, and Bulgaria. However if we're referring to Germany's new allies today, they are allies with NATO members.
If you mean who Germany's allies were. Japan, Austria, and spain were their biggest allies.
The Russians treated the Allies differently because the Allies were on their side. Both the Allies and the Russians were trying to defeat Germany. In addition, Russia had a score to settle with Germany because of Germany's invasion of Russia.
