In all the bible translations that I have checked, these are the only verses which use the word antichrist:
Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time. (1 John 2:18)
Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son. (1 John 2:22)
And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world. (1 John 4:3)
For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist. (2 John 7)
None of these scriptures identifies the antichrist or the antichrists to be any particular person. The LDS Bible Dictionary makes some interesting statements though in the entry Antichrist:
A word used by John to describe one who would assume the guise of Christ but in reality would be opposed to Christ (1 Jn. 2:18–22; 4:3–6; 2 Jn. 1:7). In a broader sense it is anyone or anything that counterfeits the true gospel or plan of salvation and that openly or secretly is set up in opposition to Christ. The great antichrist is Lucifer, but he has many assistants both as spirit beings and as mortals. See 2 Thes. 2:1–12; Rev. 13:17; Jacob 7:1–23; Alma 1:2–16; 30:6–60.
So in a broad sense, there are lots of antichrists. There are some similarities between the antichrists in the Book of Mormon and Judas Iscariot, as well as Hananias and his wife Saphira who lie to the Holy Ghost and lose their lives (see Acts 5:1-10). The similarity consists in the way they end up dying (for Judas' death see Acts 1:16-19).
