Can anyone identify these uniforms and the military decoration that looks like an x or a cross on the shorter gentleman?

The shorter gentleman is my great-grandfather. The only information I have is his name. I don't even have his DOB or DOD (although I'm speculating circa 1980's - 1940). My ancestry is all Polish so thus the assumption for Polish uniforms. I've also researched that medal and seem to keep coming back to the cross of valor that was introduced in 1920. Lastly, my family comes from South of Tarnow, Poland. Please see original image at imgur.com/a/ePZRfVO. Thank you!
