I'm hoping someone can help me identify my grandfather's WWII bars/medals.

My grandfather's WWII records were destroyed in the fire at the National Archives in 1973, so they weren't able to confirm the medals he received. I was able to identify 4 out of 5, but the blue and silver bar in the bottom middle is still a mystery. Also, it's my understanding that the purple and white bar is a Purple Heart, but my grandfather NEVER talked about the medals he received, so I'm hoping someone can confirm that the purple and white bar is in fact a Purple Heart. Thank you so much for your help!
