What decides if a helicopter gets 2/4/6 blades?

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?

Why no mention of the width of the rotor blades? I worked on hueys in a air ambulance company Uh1E? Or H any way our sister company was air assault, when I worked with those (avionics) I noticed the blades were considerably wider Uh1M.. but those birds had guns and rocket launchers. I always thought the wide blades were for firing platform stability…. maybe off there. But how does a wider wing play into the power v. Lift v. Blade length?
