Hi warlocke.
It's true that the pet you equip occupies one square in the 'circle', but the rest are occupied not by pets, but by other optional equipment you buy from the Cash Shop. You can only equip one pet at a time.
These 'CS' items as they are commonly abbreviated, may have additional stats and can be anything from robes, glasses, hats and wigs.They are worn over your normal equipment.
Also, this is the wrong section for your question. This section is for new people to inroduce themselves. There's a seperate questions section a bit further down
