There are only five angels that are named in the Bible:  Abaddon, Beelzebul, Gabriel, Michael, and Satan.  Three are fallen angels, and two serve God.

Abaddon, Apollyon

Abaddon is the Angel of the bottomless pit who appears to be a ruler of evil spirits as described in the book of Revelation.  The word used in the Old Testament is a place of destruction (Psalm 88:11; Proverbs 15:11; 27:20).

• Rev. 9:11, “They have as king over them, the angel of the abyss; his name in Hebrew is Abaddon, and in the Greek he has the name Apollyon.”

Beelzebub, Beelzebul

Beelzebul means “Lord of the flies.”  It appears to be another reference or name of Satan in the New Testament.  The word appears as a name of a false god in the Old Testament.

• 2 Kings 1:2, “And Ahaziah fell through the lattice in his upper chamber which was in Samaria, and became ill. So he sent messengers and said to them, “Go, inquire of Baal-zebub, the god of Ekron, whether I will recover from this sickness.”
• 2 Kings 1:16, “Then he said to him, “Thus says the LORD, ‘Because you have sent messengers to inquire of Baal-zebub, the god of Ekron—is it because there is no God in Israel to inquire of His word?—therefore you shall not come down from the bed where you have gone up, but shall surely die.'”
• Matthew 10:25, “It is enough for the disciple that he become like his teacher, and the slave like his master. If they have called the head of the house Beelzebul, how much more will they malign the members of his household!”
• Matthew 12:24, “But when the Pharisees heard this, they said, “This man casts out demons only by Beelzebul the ruler of the demons.”
• Mark 3:22, “The scribes who came down from Jerusalem were saying, ‘He is possessed by Beelzebul,’ and ‘He casts out the demons by the ruler of the demons.'”
• Luke 11:15, “But some of them said, “He casts out demons by Beelzebul, the ruler of the demons.”

Gabriel

Gabriel  means “man of God.”  He appears to be one who carries messages.  He is an Archangel who appeared to Daniel as a man and gave him the meaning of a vision.  In the New Testament, he appeared to Zechariah who was serving in the temple in order to announce the birth of John the Baptist.  Six months later he appeared to Mary, informing her that she would be the mother of Jesus.

• Daniel 8:16, “And I heard the voice of a man between the banks of Ulai, and he called out and said, “Gabriel, give this man an understanding of the vision.”
• Daniel 9:21, “while I was still speaking in prayer, then the man Gabriel, whom I had seen in the vision previously, came to me in my extreme weariness about the time of the evening offering.”
• Luke 1:19, “The angel answered and said to him, “I am Gabriel, who stands in the presence of God, and I have been sent to speak to you and to bring you this good news.”
• Luke 1:26, “Now in the sixth month the angel Gabriel was sent from God to a city in Galilee called Nazareth.”

Michael

Michael means “who is like God.”  He appears to be the one who does battle.  Michael battles against Satan and his angels.

• Daniel 10:13, “But the prince of the kingdom of Persia was withstanding me for twenty-one days; then behold, Michael, one of the chief princes, came to help me, for I had been left there with the kings of Persia.”
• Daniel 12:1, “Now at that time Michael, the great prince who stands guard over the sons of your people, will arise. And there will be a time of distress such as never occurred since there was a nation until that time; and at that time your people, everyone who is found written in the book, will be rescued.”
• 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!”
• Revelation 12:7-8, “And there was war in heaven, Michael and his angels waging war with the dragon. The dragon and his angels waged war, 8 and they were not strong enough, and there was no longer a place found for them in heaven.”

Satan

Satan is the adversary of God and mankind.  He is the fallen angel, the devil, who rebelled against God.  He’s mentioned many times in the New Testament.

• Matt 4:10, “Then Jesus said to him, “Go, Satan! For it is written, ‘You shall worship the Lord your God, and serve Him only.'”
• Mark 1:13, “And He was in the wilderness forty days being tempted by Satan; and He was with the wild beasts, and the angels were ministering to Him.”
• Luke 22:3, “And Satan entered into Judas who was called Iscariot, belonging to the number of the twelve.”
• Rom. 16:20, “The God of peace will soon crush Satan under your feet. The grace of our Lord Jesus be with you.”
• 2 Cor. 11:14, “No wonder, for even Satan disguises himself as an angel of light.”
• Rev. 12:9, “And the great dragon was thrown down, the serpent of old who is called the devil and Satan, who deceives the whole world; he was thrown down to the earth, and his angels were thrown down with him.”
