Looking to identify planes in grandfather's photos

I am looking to identify airplanes that are in pictures with my grandfather when he served in WWII. I have attached the pictures.

My grandfather, Bernard J Hurley, served as a Corporal in the 895th Chemical Company of the U.S. Army. He traveled to Texas, Missouri, Australia, New Guinea, the Philippines, and Ie Shima (Ie Jima), Japan.




If anyone can help, please contact me.

The cross marking composed of four 7s was used by the Imperial Japanese Army's 74th Sentai (flight squadron).
Airframe looks like a Ki-49 left in the Philippines in early 1945.

Thank you! You are so right!!
