I respectfully disagree, you seem to be basing your conclusions entirely on verses 13, 14, and 16. Wherein the reference of a 'cherub' in the 'garden of G*d in Eden' as proof of this interpretation. But reading the king of Tyre (Hiram) as a supernatural angelic figure is completely incongruent with the statement that he is 'but a man' (as opposed to 'a god'; 28.2,9) and that he would be killed by 'the uncircumcised, by the hand of foreigners' (28.10), and that his chief sin emerged from his wealthy trade (28.4-5,15-16,18). The references to the king of Tyre as a 'cherub' who was in 'Eden' should be understood as a metaphor that describes the king's great privilege and blessing, and hence just how terrible his condemnation is.
Far too often humans hide behind a devil, they accuse him of tempting and making them sin. The truth is, the devil or the satan can not do anything to you, he can not force you to sin. Only you (and you alone) can and do make the choice to follow the rules/Laws given to you by G*d, you can chose to allow others to tell you that the Laws do not apply to you, a gentile, that they were "done away with" as many did when they accepted the teachings of Saul or Pauline Christianity. But, in the end....at the time of your personal judgment, you will stand alone as the only one to answer for your own sins. The satan will not stand as your scapegoat and neither will your preacher, teacher, minister, or other religious leader; also absent will be your parents, your neighbor, or members of your gang; blaming others to include the satan will not absolve you for making damnable decisions. Your sins belong you.
As with the king of Tryre, Hiram, he and his town had it all but the prophesy came true. "Alexander did far more against Tyre than Shalmaneser or Nebuchadnezzar had done. Not content with crushing her, he took care that she never should revive; for he founded Alexandria as her substitute, and changed forever the track of the commerce of the world." (Edward Creasy, Fifteen Decisive Battles of the World, ch. 4). Tyre was rebuilt near the old site in southern Lebanon with a population of around 100,000 people, under the concrete and asphalt of the streets and roads, Alexander's "mole" can be found. But, as in prophesy, the site of the original town is no more than ruins.

Ezekiel 28: 1-10 refers to the man king of Tyre, Ezk 28: 11-19 refers to the spirit behind the king of Tyre. That would be Lucifer.
