Answering this question fully will require some spoilers, so be warned. Voldemort is obviously the main bad guy. His followers are the Death Eaters. The most prominent Death Eaters are Bellatrix, Snape, and the Malfoys. Bellatrix is evil and stays evil. Snape seems evil at first, but turns out to be a double agent on the side of good. The Malfoys are loyal to Voldemort at first, but they ultimately abandon him. There are also a lot of unnamed Death Eaters and Dark creatuers on Voldemort's side. Outside of Voldemort's forces, there's Griphook, who can't exactly be considered good since he betrayed the Trio after getting them into Gringotts.
