The first one is Dominion Cartridge (Canada). I can't say what the origins of the others are. .32 CFW is .32 Center (or Central) Fire Winchester, another name for the .32-20. So the caliber is stamped twice. The middle one is 38 S&W SPL. Without a maker stamp on two of them (UMC=Union Metallic Cartridge, WRA = Winchester, P. C. Co. = Peters, etc.) only an advanced collector could tell you who might have made them. You might want to post your question on the International Ammunition Association (IAA) forum. That would be the best way to get an answer.
