[Azimaith]

Bible gives far briefer and less indepth this is from several sources. The Book of Tobit it one, The Testaments of solomon contain a wealth of info, so do some of the more recents such as Dictionnaire Infernal by Collin De Plancy.

As for those names, those are indeed fairly rare demon names save for perhaps Nephilim.

Mara: Mara ("death" or "thirst"), also called Papiyan ("more wicked") and Varsavarti ("he who fills desires"), is the evil spirit (or sometimes as simply the personification of evil) in Buddhism who tempted Siddharta during the time he searched for the way, and as he sat beneath the Bo Tree and meditated. During this confrontation, Mara, whose attributes include blindness, murkiness, death, and darkness, attempts to guide Siddharta from the path of enlightenment by tempting him to return to his former ways.

Nephilim/ The Watchers: The nephilim refer to the fallen angels. While Genesis 6 tells that angels married women, it does not condemn this as a sin. Psalm 82 tells that the elohim sinned, but does not tell how (i.e. it does not mention that they married women). It may have been that the angels sinned by reproducing. Certain passages in Jewish Midrash talk of how angels are immortal and do not need to reproduce. Because humans are not, they must reproduce in order to achieve immortality in their descendents.

Haven't heard about the Nahema or Taurvi though..
