I know of 4

Michael
Raphael
Gabriel
Uriel

Wikipedia says this however:

Within the rabbinic tradition, the Kabbalah, and the Book of Enoch chapter 20, and the Life of Adam and Eve, the usual number of archangels given is at least seven, who are the focal angels. Three higher archangels are also commonly referenced: Michael, Raphael, and Gabriel. There is confusion about one of the following eight names, concerning which one listed is not truly an archangel. They are: Uriel, Sariel, Raguel, and Remiel (possibly the Ramiel of the Apocalypse of Baruch, said to preside over true visions), Zadkiel, Jophiel, Haniel and Chamuel.[2]
