I'm a beginner at Russian, but I'll give it a shot; from top to bottom:
"Mother Russia Calls" while holding a paper reading "military oath".
Mother at point of bayonet: "Warriors of the Red Army, HELP!"
Soldier, sailor, old couple: "The defenders of the city of Lenin" (ie. Leningrad)
Old fellow with 91/30: "Our forces have no end"
Soldier striking down a sign with the butt of his rifle: "To the West!" while the sign reads "East - To Vostok".
The soldier holding an SVT up is saying something about Moscow, but "otstoim" isn't in my dictionary.
Soldier holding PPSh: "You have returned to us!"
Soldier rolling a cigarette in front of "Hitler's Germany" sign under stahlhelm: I think this is a colloquialism, meaning something similar to "Just like we meant to".
Again, something like: "The proper end for a Fascist beast".
"The Red Army - glory!"
Hitler menaced by flags: "He doesn't like this!"
Russian seems to have a whole bunch of related sayings that depend on a story behind them, and unless you know the story, the saying doesn't make sense, but these are my best try at the posters.
