I recently acquired these four medals. I was wondering if anyone could help me identify them, and then point out any things that may suggest it’s a counterfeit? The reason I have questions about the authenticity is that the ribbons are so new. The green medal is also made of really light feeling metal, I feel if I press hard enough I may be able to bend it. I was told it was not a military war medal, but a civilian war medal, so maybe they saved on the cost of those medals?

I posted the album below. Thank you in advance!
