As the title says, why do Hueys have 2 blades, while most others have 4, or the Sea Stallion has 6? And if you put 6 on a 4, does that mean more lift and better performance?

It’s about how much lift you need. The current versions of the H-1 (UH-1Y and AH-1Z) now have 4 blades, which added 7,000 lbs to the max gross take-off weight of the UH and 4,000 lbs to the max gross take-off weight of the AH. This was done in conjunction with uprated transmissions and engines.
