How does the New Testament describe "angels"?

In the New Testament, "angels" is "separate and distinct
ministering spirits: of God's creation. Angels are not glorified
human beings. Matthew 22:30 explains that they do not marry or
reproduce like humans; and Hebrews 12:22-23 says that when we get
to the heavenly Jerusalem, we will be met by "myriads of angels"
and "the spirits of righteous men (and women) made perfect" ---
these are two distinct groups!!!
