. . . .The Latin word lucifer seems to have been carried over from the Latin Vulgate to the KJV in Isaiah 14:12, and became a Protestant proof text for the fall of Satan. Isaiah 14:12 is actually speaking of a Babylonian king.
The Latin Vulgate does not use lucifer or luciferum as a proper name. It is used as a description.
The Douay-Rheims translated lucifer and luciferum into English, as day star in every passage except Isaiah 14:12–where the Latin word lucifer is retained.
Douay-Rheims: Isaiah 14:12 How art thou fallen from heaven, O Lucifer, who didst rise in the morning? how art thou fallen to the earth, that didst wound the nations?
King James Version: Isaiah 14:12 How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!

Latin Vulgate: 2 Peter 1:19 “et habemus firmiorem propheticum sermonem cui bene facitis adtendentes quasi lucernae lucenti in caliginoso loco donec dies inlucescat et lucifer oriatur in cordibus vestris”
Douay-Rheims: 2 Peter 1:19 And we have the more firm prophetical word: whereunto you do well to attend, as to a light that shineth in a dark place, until the day dawn and the day star arise in your hearts.
Latin Vulgate: Isaiah 14:12 “quomodo cecidisti de caelo lucifer qui mane oriebaris corruisti in terram qui vulnerabas gentes”
Douay-Rheims: Isaiah 14:12 How art thou fallen from heaven, O Lucifer, who didst rise in the morning? how art thou fallen to the earth, that didst wound the nations?

There was actually a bishop named Lucifer, known as Lucifer of Cagliari. He was born in the early part of the 4th century and died in 371 A.D. Link:

Also, the word lucifer is used in Roman Rite liturgy’s Exultet chant in praise of the paschal candle and refers to Christ as the Morning Star (in Latin, lucifer, with lower-case initial): “. . . . . .Flammas eius lucifer matutinus inveniat:Ille, inquam, lucifer, qui nescit occasum:Christus Filius tuus,qui, regressus ab inferis, humano generi serenus illuxit,et vivit et regnat in saecula saeculorum.”

. . . (separation of lines and emphasis is mine throughout)
"Lucifer (Hebr. helel; Septuagint eosphoros, Vulgate Lucifer) originally denotes the planet Venus, emphasizing its brilliancy.
The Vulgate employs the word also for “the light of the morning” (Job, xi,17),
“the signs of the zodiac” (Job, xxxviiii, 32), and “the aurora” (Ps., cix, 3).
Metaphorically, the word is applied to the King of Babylon (Is., xiv, 12) as preeminent among the princes of his time;
to the high priest Simon son of Onias (Ecclus.,1, 6), for his surpassing virtue;
to the glory of heaven (Apoc., ii, 28), by reason of its excellency;
finally, to Jesus Christ himself (II Petr., i, 19; Apoc., xxii, 16; the “Exultet” of Holy Saturday), the true light of our spiritual life.
The Syriac version and the version of Aquila derive the Hebrew noun helel from the verb yal4l, “to lament”; St. Jerome agrees with them (In Is., i, 14; P.L., XXIV, 161), and makes Lucifer the name of the principal fallen angel, who must lament the loss of his original glory bright as the morning star. In Christian tradition this meaning of Lucifer has prevailed; the Fathers maintain that Lucifer is not the proper name of the devil, but denotes only the state from which he has fallen (Petavius, “De Angelis”, III, iii, 4). . . ."
