For starters, I think every one of them would have corrosive priming. Also, it would be 50-50 that the 1938 ammo would go off, decreasing proportionally as they get older, with the possibility of the 1918 being close to "0". (The 43 would probably go off.)
Red, if I recall, is tracer, black is generally armor piercing, and I don't recall what green is.
I'm not into cartridge collecting, but the rounds probably have some value to a collector; However, I don't think you're going to retire.
