Angel: is probably the same as a god or divine being: not necessarily God, so a divine being other than the Father. The ‘el’ on the end of ancient names, which is a star symbol in ancient cuneiform as used by Daniel who told us much about angels, signifies dignitary, noble, ‘star’ or ‘aristocrat’, but also divine being, god, angel. Sons of God is the term in Genesis and Job. Daniel saw several who he described as like a man, but seen in a heavenly context, sometimes a vision. One of these was described in Revelation in exact same terms as in Daniel. That one is identified in Revelation as Jesus. So John is telling us it is the person seen by Daniel. Similar to a human before incarnation but also similar to an angel.
