yeah great question tbh....heres a bit about me !!
there are six of us here in this awful brain soup...there is I, the host, whom you have supposedly already read about above. There is Eddie, an old alter we didn't know about who has re-emerged due to a hyperfixation on his source media - he is an introject of Eddie Munson - his role is unknown ? Then there is Bill who has been around 5everrrrr, he is a soother and protector and acts as a dad to us all. There are are Will, Seeley, and Luna, and I can't be assed typing about them...(in short, Seeley = MH symptom holder and introject of Seeley Booth, Will = trauma holder and introject of Will Byers , Luna = helper alter? she helps Bill with his jobs pretty much - she's semi brain made and semi introject of Luna Lovegood)
