Iblis

May I know about the structure of the infernal court of Iblis? obviously if it exists, because I read about the Sea of ​​Darkness (Bahru 'z-Zulmat) and so I was wondering about some sort of hierarchy under iblis

My dad told me an interesting thing in Quran, that God refers to him as Iblis when he is tempting himself and demon/shaytan when he is tempting others, this is really interesting, but should we add it to his page or is it irrelevant?
