The two automotive on the top row are commonly known as Omega keys as that was the brand name they typically wore. They were Yale products and I thnik for Ford. The purpose of the offset may have had many uses but the May, 1933 patent 1,906,701 claims pick resistance.
The third from the left on the bottom row is a Chicago Hardware key blank, not to be confused with the Chicago Lock Co. I would be interested in owning that key as I have a couple of blanks but they are both the same keyway and I’m not sure a match for that one.
