Grandfather flew in the pacific theater in WWII, but never talked much about it. Any help?

Apologies that this is the best photo I’ve got of his medal box. He passed a few years back, and while I know he flew Thunderbolts and Mustangs in the pacific theater as part of the 460th fighter squadron, he never talked much about what he actually did or shared many stories from that time. I was hoping to get some help identifying what these are and maybe get a better understanding of what he did to earn them.
