Hi, does anyone have a /players command that will show in chat how many players are online? and with names and will show what clan they in if they are in a clan?

The Player List plugin. If the clans are stored in names, sure, otherwise no.

well im guessing they will be stored in names. idk I saw a server have this when you do /players you can see who is online by name in chat box and would show there clantag in there names

As Wulf just said, Player List is the one you want, it uses the /players chat command.
