Glorificus aka Glory - Main 'baddie' Season 5
Gregor of the Knights of Byzantium has kindly explained some of Glory's history to us:
"Along with the Beast, they were a triumvirate of suffering and despair, ruling with equal vengeance. But the power of the Beast grew beyond even what they could conceive -- as did her lust for pain and misery. They looked upon her, what she had become... and trembled ...Such was her power. They feared she would attempt to seize the dimension for herself, and decided to strike first. A great battle erupted. The very bowels of Hell trembled as the war of the gods spanned a thousand years. In the end, they stood victorious over the Beast - barely. She was cast out, banished to this "lower" plane of existence, forced to live and ultimately die trapped within the body of a mortal, a newborn male, created as her prison. Her own living Hell ...That was her punishment. To finish an ageless existence buried deep inside the flesh tomb of a normal average human man. A man that would grow, age, and eventually die, like all the rest of us. That is the Beast's only weakness. ...You have seen a glimpse of the true Beast. Her power was too great to be completely contained. She's found a way to escape her mortal prison for brief periods before her energies are exhausted and she's forced back into her living cell of meat and bone."
It turned out that Glory and Ben were the sharing the same body. He was her host. Giles killed Ben when Buffy couldn't, thus killing Glory as well.

Harmony Kendall - (as a vamp) Season 4/5
Harmony was a popular Sunnydale High student before she was turned to a vampire (presumably during Graduation Day, part II). As a vampire, she's vapid and attempting to turn herself into a tough force to be reckoned with. For awhile she lived with Spike in his crypt, but once Drusilla returned (even for the brief period she was there) - Spike kicked her out. Harmony fled to Los Angeles, where she stayed for at least a night with Cordelia. However, Harmony betrayed them (no surprise) to a bunch of vampires. Cordelia couldn't bring herself to kill Harmony. Harmony remains at large in Los Angeles.

Hus - Pangs

Regular, if mean, students who were possessed by the spirit of hyenas. They behaved like animals and ate Principal Flutie. They were de-possessed at the end of The Pack. It is unknown what happened to the actual students, however.
