The angel Phanael appears in the grimoires The Discoverie of Witchcraft, Five Books of Mystery, and Book of Enoch
From Book of Enoch:
The second is he who presides over every suffering and every affliction of the sons of men, the holy Raphael. The third, who presides over all that is powerful, is Gabriel. And the fourth, who presides over repentance, and the hope of those who will inherit eternal life, is Phanuel. These are the four angels of the most high God, and their four voices, which at that time I heard.
