The number 7 is mentioned throughout the Bible. Recently I read an article dealing with the 7 raptures ( 5 have already come to pass and 2 more are waiting to happen). The first 5 involved: Enoch, Elijah, Moses, Christ, and the old testament saints. The future raptures involve the Church and the two witnesses mentioned in the Book of Revelation. Jesus Christ is right in the middle of all the 7 raptures as represented in the Menorah. Is this a true Biblical teaching?
The rapture is a unique event where all living believers will suddenly be taken to be with the Lord without dying first (1 Thes. 4:16-17). There is only one of these. It is the rapture of the Church which will take place before the end times judgments begin. There are several other events that are considered models or types such as Enoch and Elijah who also went to be with God without dying first. All the others you mention are models of the resurrection, where believers who have died come back to life. Jesus is the prototype of the resurrection.
