The top right one is a round leather belt punch and cutter for splicing leather drive belts on sewing machines, lathes, etc.
The top left one is an eyelet punch/press for shoe eyelets.
The right middle one could be a leather or a paper punch; I think they were marketed as either. Is the blade round or flat? If flat, it is probably for punching a slot in leather. If round, it is either paper or leather punch.
The bottom right one is a new one for me. It looks like it clamps some kind of ferrule or fastener maybe.
The bottom left looks like a parallel jaw pliers with a fine adjust/catch on it.
