The notion of Fallen Angels is not found in The Old Testament. In books like Job, the God appointed adversary is ha-satan (meaning The Adversary and the title of an office, not the designation or name of an angel) The possible exceptions are 1 Chronicles 21 and 2 Samuel24, where Satan seems to emerge as a distinct personality and is identified by name; but scholars are inclined to believe that in these 2 instances the definite was inadvertently omitted in translation and that the original read "The Satan". i,e., "The Adversary".
In the New Testament, specifically in Revelations 12, the notion of a fallen angel and of fallen angels is spelt out:
"And His Tail(Satan's) drew the third of the stars of heaven(Angels) and did cast them down to earth... and Satan, which deceiveth the whole world; he was cast out into the earth and his angels were cast out with him".
Enoch 1 claims that 200 fell, naming about 19 and listing "Chiefs Of Ten", the most prominent among them being Semyaza, Azazel, Sariel, Rumiel, Danjal, Turel, Kokabel.
William Auvergne, bishop of Paris (1228-1249) in his De Universo held that , of the 9 orders that were created , "a 10th part fell" from each order and that in their fallen state they retained their relative rank
