I want to join rugby, and i was just wondering, do the make rugby cleats or should i wear some other sport cleats... Correct me if they even use cleats cu i dont know

There are many, many types rugby-specific boots available with studs designed especially for rucking and scrumming. The number, size and placement of the studs will vary with a player's position and the field conditions of the day. Just google "rugby" and "footwear". Soccer boots are also acceptable, particularly for wingers.
