In the Old Testament, Satan was actually simply a servant of God, and is referred to in Jewish texts as the Accuser. Basically, a like a prosecuting attorney. He never acted against God's will, though he disagreed with God.
The name Lucifer is from Isaiah: Isaiah preaches against a villainous babylonian king, and at one point refers to him as Morningstar, which translates to Lucifer. Later interpretations somehow decided that Isaiah was speaking about a fallen angel, even though the passage is quite clearly talking about a mortal king, especially when given full context.

Basically, what we view as Satan/Lucifer today is a combination of a stories about a perfectly obedient angel who acted as a 'devil's advocate' for God, a Caananite myth about the Morning Star, a babylonian king, some creative interpretation by both Jewish and Christian early (slightly pre AD and early AD) writers, and a whole lot of fictionalization by later poets.

Can be he a devil's advocate if there was no devil at that time?.....
