In this first section, we have a prophecy to a "Prince" of Tyre and by the description it's clearly a man...
Ezekiel 28:22 Son of man, say unto the prince of Tyrus, Thus saith the Lord God; Because thine heart is lifted up, and thou hast said, I am a God, I sit in the seat of God, in the midst of the seas; yet thou art a man, and not God, though thou set thine heart as the heart of God:
But then the prophecy continues on to Ezekiel 28:12, where another prophecy is given to a "King" of Tyre. But by comparing Ezekiel 28:2-11 to the following passage, this "king" is clearly not a man...
Ezekiel 28:12-1312 Son of man, take up a lamentation upon the king of Tyrus, and say unto him, Thus saith the Lord God; Thou sealest up the sum, full of wisdom, and perfect in beauty.
13 Thou hast been in Eden the garden of God; every precious stone was thy covering, the sardius, topaz, and the diamond, the beryl, the onyx, and the jasper, the sapphire, the emerald, and the carbuncle, and gold: the workmanship of thy tabrets and of thy pipes was prepared in thee in the day that thou wast created.
...So this "king" was old enough to be present in Eden, and was perfect in beauty...
Ezekiel 28:1414 Thou art the anointed cherub that covereth; and I have set thee so: thou wast upon the holy mountain of God; thou hast walked up and down in the midst of the stones of fire.
This "king" was also a class of (what we call) angel called a "cherub", who's primary function was "to cover"...but to cover what? Well if we pause Ezekiel's passage for a moment and reference Exodus 25:17-22:
Exodus 25:17-2217 And thou shalt make a mercy seat of pure gold: two cubits and a half shall be the length thereof, and a cubit and a half the breadth thereof.
18 And thou shalt make two cherubim of gold, of beaten work shalt thou make them, in the two ends of the mercy seat.
19 And make one cherub on the one end, and the other cherub on the other end: even of the mercy seat shall ye make the cherubim on the two ends thereof.
20 And the cherubim shall stretch forth their wings on high, covering the mercy seat with their wings, and their faces shall look one to another; toward the mercy seat shall the faces of the cherubim be.
21 And thou shalt put the mercy seat above upon the ark; and in the ark thou shalt put the testimony that I shall give thee.
22 And there I will meet with thee, and I will commune with thee from above the mercy seat, from between the two cherubim which are upon the ark of the testimony, of all things which I will give thee in commandment unto the children of Israel.
There is no other place (I can find) in scripture where cherubs are associated with "covering" except the throne (mercy seat). Other places cherubs either guard or bear the Lord as a chariot...so if this "king" was "
a cherub who covers" then he was of a rank so high that he was one of only two beings that stood beside and covered the very throne of God; a throne that's in the most holiest place of heaven. So this "king" possibly stood by the Most High God of all creation.
[Now if we extrapolate more information from the fact that Christ, The Son, is at God's right hand then it’s probable this "king" was the one figuratively at God's left hand...possibly (if we are to rely on the tabernacle furnishings of the mercy seat as an image of heavenly truth). And if his nature is "to accuse" (i.e. judgment), to me - at least - the left hand would be fitting because as Christ's nature is "to have mercy", this would fit the figurative "arms" of God (judgment and mercy)...but this is just a side study of mine and not completely relevant to the identity of this being we call "Lucifer".

Continuing with Ezekiel 28...
Ezekiel 28:1515 Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee.
16 By the multitude of thy merchandise they have filled the midst of thee with violence, and thou hast sinned: therefore I will cast thee as profane out of the mountain of God: and I will destroy thee, O covering cherub, from the midst of the stones of fire.
This "king" was perfect until iniquity was found in him, and he was to be "cast out". There is only one main rival in the gospels (Luke 10:18) and Revelation 12 who's associated with being "cast out" of heaven, and that was "The Dragon", "Hasatan". Continuing with Ezekiel 28...
Ezekiel 28:17-1917 Thine heart was lifted up because of thy beauty, thou hast corrupted thy wisdom by reason of thy brightness: I will cast thee to the ground, I will lay thee before kings, that they may behold thee.
18 Thou hast defiled thy sanctuaries by the multitude of thine iniquities, by the iniquity of thy traffic; therefore will I bring forth a fire from the midst of thee, it shall devour thee, and I will bring thee to ashes upon the earth in the sight of all them that behold thee.
19 All they that know thee among the people shall be astonished at thee: thou shalt be a terror, and never shalt thou be any more.
Now while there are passages that refer to the "angels" as "morning stars" (which shine), in Isaiah 14:12 there is a particular "shining one" ("helel", translated "Lucifer") being prophesied against who has "fallen from heaven". So while the word "lucifer" doesn't appear to be a proper noun, it was a designation for this heavenly being who fell.
So in the Ezekiel prophecy this "king" - who was a “
bright” covering cherub - defiled himself and was to be
cast down from heaven...and then after that, is to be “
brought to ashes (i.e. burned)” for all to witness. This is exactly what the following Revelation prophecy say happens to satan.
Revelation 12:9-10; 20:10And the great dragon was cast out, that old serpent [a call back to Eden], called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night.
20:10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
The Dragon, That “old serpent” (a call back to Eden), The devil, satan is cast out...and then later he is hurled in the lake of fire. So this passage links to Ezekiel's passage; satan is the same as "the old serpent from Eden" and the same as "the King of Tyre" and "the cherub who covered", so he was an angel formerly of such a high rank that he had a presence in the most holy place. He was/is an angel of such beauty and brilliance that he allowed himself to become vain; prideful and he fell.
2 Corinthians 11:14And no wonder, for Satan himself masquerades as an angel of light.
