1. Yes, Jesus was a spirit before coming to earth. His name was the Word.
The Word wasn't his name, it was a descriptive title. It means that he was a spokesperson, or representative of his Father, Jehovah. John 12:50 And yes, Revelation 19:13, may, according to your translation, read "the name he is called is the Word, but that isn't literal." No one called him by the name Word. "Hey, Word . . ." they didn't say "What's up?"
2. No, Jesus was not created. Both the Word and the Father existed eternally.
3. Jesus was not created and was not an angel
Colossians 1:15; Revelation 3:14; John 1:14; Philippians 2:7
4, Can't say who has authority over angels
Jehovah, Michael and Jesus. Job 1:6; Revelation 12:7; 1 Thessalonians 4:16; 2 Thessalonians 1:7: Matthew 24:30, 31:
5. Don't know what Jesus voice is like.
1 Thessalonians 4:16
6. Don't know if there could be other archangels.
Michael is named five times in the Bible; Daniel 10:13; Daniel 10:21; Daniel 12:1; Jude 1:9; Revelation 12:7; Arch as a prefix means "chief; principal" and the term archangel is never found in the plural. The only other angel mentioned by name is Gabriel.
1. Jesus existed in heaven before he came to earth. Proverbs 8:22 / John 1:1,3, 14; 3:13; 8:23, 58; 17:5 / Colossians 1:15-17 / 1 John 2:13 / Revelation 3:14 all speak of Jesus’ existence before the world began, in fact before anything was created Jesus was created. Before Heaven, the heavens, the Earth, and of course, man. He is the firstborn of creation, the beginning of creation, he came from somewhere other than this world, he descended from heaven. There can be no doubt that he had a pre-human existence in heaven before he came to Earth as the man Jesus Christ.
2. Jesus’ position in heaven before he came to the earth must have been an important one, considering he was the first of Jehovah’s creation and all things were created through him and for him. (Proverbs 8:22 / John 1:3) That means not only the heavens and earth as we know them but the angels and heaven as well. Jesus is referred to as the "word of God," this means he is the spokesperson. (John 1:1) As the spokesperson for Jehovah God we can assume that when an angel performed some important task on earth, like guiding and protecting the early Israelites from Egypt or taking the physical form of men in performing an important task, it was likely Michael as he existed before he came to earth as Jesus.
3. The term archangel means chief of the angels. Arch means chief or principal. The term is only applied to one angel in the Bible. Michael. It is always used in the singular. There is only one archangel. The term archangel itself only appears twice throughout Scripture. At 1 Thessalonians 4:16 Paul writes of Jesus as having the voice of the archangel, and Jude 9 indicates Michael disputed with Satan over the body of Moses. So there is a connection with Jesus as well as an indication that Michael was connected in some way with the people of the exodus of Egypt.
4. Other than Jehovah God himself only two people in the Bible are said to be in charge of or over the angels. They are Michael and Jesus Christ. The name Michael appears only five times throughout Scripture. At Daniel 10:13, 21; 12:1 / Jude 9 and Revelation 12:7.
5. Are there any others who believe Michael and Jesus are the same? Yes, there are many. Joseph Benson, E. W. Hengstenberg, J. P. Lange, Butterworth, Cruden, Taylor, Guyse all wrote that Michael and Jesus were the same.
Clarke's Commentary (Adam Clarke) - "Let it be observed that the word archangel is never found in the plural number in the sacred writings. There can be properly only one archangel, one chief or head of all the angelic host .... Michael is this archangel, and head of all the angelic orders .... hence by this personage, in the Apocalypse, many understand the Lord Jesus."

The International Standard Bible Encyclopaedia: - "The earlier Protestant scholars usually identified Michael with the preincarnate Christ, finding support for their view, not only in the juxtaposition of the "child" and the archangel in Rev. 12, but also in the attributes ascribed to him in Daniel" – vol. 3, p. 2048, Eerdmans Publishing, 1984 printing.

Brown's Dictionary of the Bible - on 'Michael' and 'Angel,' both these words do sometimes refer to Christ; and also affirms that Christ is the Archangel.
The NIV Study Bible - "The Angel of the LORD .... Traditional Christian interpretation has held that this 'angel' was a preincarnate manifestation of Christ as God's Messenger-Servant. It may be ..., the angel could speak on behalf of the One who sent him." - footnote for Gen. 16:7. Zondervan Publishing, 1985
