Is Michael the only archangel in the Bible?

The title of archangel is only found two times in the Bible.  The first is 1 Thessalonians 4:16 where it talks about the rapture and Jesus having the voice of an archangel (this is not saying that Jesus is an archangel, but will have the voice of one).  The second is found in Jude 1:9 where it gives Michael the title of archangel.  Many try to say that Gabriel is an archangel, but there is nothing in the Bible that supports this.  Gabriel was only a messenger who delivered information to whom God chose.  There may be more archangels than Michael in Heaven, but he is the only one mentioned in the Bible.
