To quote a very good answer in wikianswers: There are several different versions and translations of the Bible. Michael is the only angel explicitly described as an archangel. Gabriel is also generally considered an archangel even though he is never directly called one. Some versions of the Bible, most notably the Catholic canon, included the Book of Tobit which features Raphael. Uriel is feature in the Book of Enoch, which appears in the Ethiopian Orthodox Bible. These two are both widely considered archangels. Enoch also features Raguel, Zerachiel and Remiel as the additional archangels. However, this is not a definitive list. Because different denominations of Christians have different versions of the Bible and different ways of interpreting it, there is no one answer for this.
The word archangel is used only twice in all of Scripture and Gabriel isn’t mentioned as being one of them. 1 Thessalonians 4:16 “For the Lord Himself will descend from heaven with a shout, with the voice of the archangel and with the trumpet of God, and the dead in Christ will rise first.” Jude 9 “But Michael the archangel, when he disputed with the devil and argued about the body of Moses, did not dare pronounce against him a railing judgment, but said, “The Lord rebuke you!” Seeing that this question was asked in the Jehovah’s Witness section I would imagine that it pertains to the Witness belief that Michael is Jesus. He’s not, pure and simple. In 1 Thess 4:16, Jesus is identified as who He is. All these things mentioned in this verse are “with” Christ: “a shout,” “the voice of the archangel,” and “the trumpet of God.” If this verse is saying that Jesus is an archangel because the voice of the archangel is with Him, then we must also say that Jesus is “a shout,” and “a trumpet”!

First, it is helpful to understand more about THE Archangel. The scriptures tell us that the foremost angel, both in power and authority, is the Archangel. (1 Thessalonians 4:16; Jude 9) The prefix “arch,” means “chief” or “principal,” http://www.biblestudytools.com/lexicons/greek/kjv/archaggelos.html and implies that there is only ONE archangel, the chief angel; in the Scriptures. Further implying that there is only one archangel is that the word “archangel” is never found in the plural. So this evidence demonstrates that there is only ONE Archangel. (Although Gabriel is the only holy angel other than Michael named in the Bible, Gabriel is never mentioned in Scripture as being called the Archangel the way Michael is at Jude 9). Of further interest, there are correspondencies within the books of Daniel and Revelation establishing that Michael is actually God’s Son before he left heaven to become Jesus Christ and also after his return to heaven. So when the voice of the resurrected Lord
