Aspects or Spirits?

Diane Vera’s “Greetings to the Legions of Hell” refers to Iblis, Lucifer, Belial, and the Ancient Serpent. I’m wondering whether these are seen–in the Church of Azazel’s paradigm–as distinct entities, or aspects of Satan. In other Satanic idioms, the spirits associated with the four directions are sometimes aspects of the Satanic Whole, but the CoAz “is polytheistic with a leaning toward hard polytheism” (from this page), and the Rising Gods of the West seem to be portrayed as distinct entities, though less important or perhaps less multi-faceted than Satan/Azazel. I’m just wondering how the Church of Azazel, and perhaps other Theistic Satanists on this forum, view the names/spirits associated with the cardinal directions.
