"Night of the Demons"
Here's one of the descriptions
Ten teens decide to have a party at an abandoned funeral parlor called Hull House. Hull House is on a strip of land rumored to be unclean and unfit for human inhabitance. The house has a nasty history to it including a the Hull family being murdered. After the ten kids enter the house they decide to have a sťance. After an attempt for the sťance they awaken a demon that lives in the basement. It possesses one of the girls then from her everyone else becomes possessed and killed by demons that inhabit the land.
Unfortunately your description fits dozens of "dead teenager" movies. Can you at least remember any specific deaths? Survivors?
Night of the Demons IIRC, had a girl and a black guy as the survivors.
