They are for 1) fighting with other roosters to prove his supremacy, and become the leader of the hens. and 2) for aiding hium so stay on the hens when they are mating.

No. The rooster is the male, the hen is the female. Some rooster breeds do not grow spurs at all.
On a Rooster, Spurs refer to the spike (or claw) protruding outward from their feet/legs.

A rooster spur is the bony like horn that grows on his legs which he uses for fights with other roosters. Some hens may also grow smaller spurs.
Defensive weapons. Roosters fight and defend by kicking, the spurs are meant just for that purpose.

spurs are hard knobs on the rooster's legs, near the feet. They are often pointed and can be quite long.
no. but they will peck and they do have talons on the feet. thay have spurs not talons.
Roosters with spurs are a throw back to the ancient breeds of chickens that had to defend themselves in the wild. The spurs are a defense mechanism that they can use to fend off predators.
It really would depend on the size of the rooster. Spurs will grow to a certain length and then start to curl. They will curl more than once but it is hard on the bird. Walking becomes difficult. Trimming spurs is not that hard.
