1946 '47 '48 Chrysler, Royal, Windsor were 6cly., Saratoga and New Yorker were staight 8 cly. It might be an Imperial as well.
Check the center vertical bar in the grill of the subject. It is diferent than the Chrysler. I am thinking Desoto.
I'm far, far from an expert... but just for fun, and without looking at any other sites, here's my guesses for cars in this pic, nearest to farthest: 39 Studebaker? 40 Chevy 38 Chrysler 40 Caddy 42 Chrysler with a 6-cyl motor (hood not long enough for an 8) I'm probably wrong on at least half of those...
