Angels are referred to in the Apocrypha by the proper names of Jeremiel, Raphael, & Uriel as well as referred to as angel and archangel. The number of occurrences is 77.
There are 18 Apocryphal books listed in the New Oxford Annotated Bible, RSV/NRSV.
Five of these books (I Esdras, Judith, Baruch, Prayer of Manasseh, and Psalm 151) have no references to angels. Eleven of the remaining thirteen books(Additions to Esther, Wisdom of Solomon, Ecclesiasticus, Letter to Jeremiah, Prayer of Azariah, Susanna, Bel and the Dragon, and 1,2,3, & 4 Maccabees) have three or fewer mentions. The preponderance of apocryphal references to angels are cited in 2 Esdras (23 references) and Tobit (34 references).

The Apocrypha was written in three locations, Egypt, Jerusalem/Palestine and in the diaspora. This was done between c.300 BC and c.90 AD. The languages of Hebrew/Aramaic and Greek were used in the . original compositions. The two principle "angelic" books, 2 Esdras & Tobit were written in Jerusalem & Syria, both early and late. They do share a common language of composition, Hebrew. "Angelic" use seems to have little Egyptian or Greek language roots.
"Angel" or the proper names for an angel, appears infrequently in the Hebrew Bible (30 references/9 books), and commonly in the New Testament (86 references/18 books). New Testament usage appears more concordant with the Apocryphal use. Apocryphal use of angels appears to be a bridge between the Hebrew Bible and the New Testament.
In the book of Tobit, the angel Raphael is God's agent who heals and frees. The angel Uriel is Ezra's teacher, director and interpreter in the book of 2 Esdras. Angels in the Apocrypha appear to be representative of a transcendent God. The development of angelology with the Apocrypha is consistent with the themes of the existence of evil, dependence upon human agencies, understanding of the supernatural, as well as transcendence.
Tobit is Canon in the Roman Catholic Bible and Eastern Orthodox Bible, but non-Canonical in the Hebrew and Protestant Bibles. Anglicans consider it Apocryphal. 2 Esdras (4 Ezra) is considered part of the Roman Catholic Canon, non-Canonical in Protestant and Eastern Orthodox Bibles, and Apocryphal in the Anglican Tradition.
The common use of angelic representations is in art. Substantive use of angels in art are recreations of biblical accounts. Angels are popular in decorative use.
