Offhand, the one I recognize first is the upper left-hand one. I'm sure that's a WWII Asiatic-Pacific Campaign ribbon. The little bronze Service Star would indicate the recipient served in that campaign.
You’re right. Seems to be a mixture.
Next to that is the American Campaign Medal, then the American Defense Medal.
Middle bar - American Forces Reserve Medal ( light blue / white ) Navy Good Conduct with 3 service stars, Army Good Conduct
Right / Top bar - Occupation Medal, WWII victory medal, National Defense Service Medal
The WWII victory medal uses the same colours as the WWI victory medal and a website I used yesterday stated that the American Campaign Medal was WWI, whereas it appears to be WWII
It would be almost impossible, at least in the British Service, for a single soldier to have all three medals in the middle bar.
