The Bible gives the names of just two angels.
Daniel 8:16 And I heard a man’s voice between the banks of Ulai, which called, and said, Gabriel, make this man to understand the vision.
Daniel 9:21 Yea, while I was speaking in prayer, even the man Gabriel, whom I had seen in the vision at the beginning, being caused to fly swiftly, touched me about the time of the evening oblation.
Luke 1:19 And the angel answering said unto him, I am Gabriel, that stand in the presence of God; and am sent to speak unto thee, and to shew thee these glad tidings.
Luke 1:26 And in the sixth month the angel Gabriel was sent from God unto a city of Galilee, named Nazareth,
Daniel 10:13 But the prince of the kingdom of Persia withstood me one and twenty days: but, lo, Michael, one of the chief princes, came to help me; and I remained there with the kings of Persia.
Daniel 10:21 But I will shew thee that which is noted in the scripture of truth: and there is none that holdeth with me in these things, but Michael your prince.
Daniel 12:1 And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book.
Jude 1:9 Yet Michael the archangel, when contending with the devil he disputed about the body of Moses, durst not bring against him a railing accusation, but said, The Lord rebuke thee.
Revelation 12:7 And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,
Jude supplies the information that Michael is the archangel but whether that makes him senior to Gabriel cannot be determined.
Revelation 12:7 is not to be understood as a literal battle between the archangel Michael and the dragon in heaven.
Angelic seniority is of no importance as far as the gospel is concerned. What is important is that we believe Gabriel’s testimony concerning Jesus Christ and the kingdom of God and take the necessary steps to obey the gospel.
Luke 1:30 And the angel said unto her, Fear not, Mary: for thou hast found favour with God. 31 And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS. 32 He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David: 33 And he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end.
I hope you have found this helpful.
