I don't recognize the one in the top photo, top right. Otherwise looks like a a couple Arrow Harts & A Hubbell from the 20's-50's and a GE from someplace in the 70 or 80's
Bottom photo left to right looks like a mid 1990's common Leviton, then a Bryant (or Smith/Stone, assuming these are Canadian) hospital grade, I don't recognize the next one and on the far right, I'd say undeniably GE, but not like one I've seen in the states

photos of the back sides would add to the thread as well smile
