The clan leader is the first in charge in warrior cats. He/She makes orders to the clan and the clan is supposed to obey. They are called chieftains or patriarchs.
To fight, protect and serve their clan even at the cost of their life. Stay loyal to your clan.
The size varies but ThunderClan has the biggest clan.
The clan where warrior cats go when they die is called StarClan. It is a group of the spirits of deceased warriors, leaders, and medicine cats who watch over and guide the living cats of the forest.
I mean Thunder clan like from the warrior series but you should have 15-20 cats in that clan

A ceremony consists of an apprentice being accepted as a warrior, or a kit being old enough to become an apprentice. Apprentice to warrior - The apprentice is brought up before the Clan to receive their warrior name and rank from the Clan leader. They must say "I do" to questions asking for their loyalty and courage. The Clan leader then gives the apprentice their new name, and the new warrior will spend the night on camp watch. Kit to apprentice - The kit is brought up before the Clan to receive their apprentice name and rank from the Clan leader. They must say "I do" to questions asking for their loyalty and courage. The Clan leader then gives the kit their new name, and the new kit will move into the apprentice's den.

A human can't but a rogue or a loner could join a Clan.
