first one says, "During a drive in Bitburg".
third one says, "As a remembrance of your comrade (and the guy's name)".
fourth looks like, "1.2.42 Bamberg" (a town in Barvaria)
the second i can't read and the rest i'll try if someone hasn't beat me to it when i get back. i'm being yelled at. we're going out for lunch!
