I can't name them all because that is a hard question my young padawan... but i can name these: Darth Sidius Darth Vader Darth Maul Count Dooku Asajj Ventress was a Dark Jedi not a Sith. Ignore this answer. Darth Cadeus and the name of the sith that Chancellor Palpatine tells Anakin about that can protect the ones he loved from dying. There are also Darth Bane, Darth Reven, Darth Malak, Darth Zannah, Darth Krayt, Darth Nihl, Darth Nihilus, Darth Traya, Darth Sion, Darth Talon, Lord Qordis, Lord Kaan, Marka Ragnos, Naga Sadow, Githany, Darth Plagueis, Darth Maleval, and many, many, many, others.
