From section , we know that Michael came as Enoch, Isaac, Ezekiel, Elisha and once as the prince of the army of Jehovah:
No, but I as the prince of the army of Jehovah, I have now come (Joshua 5:14),
before he came as Jesus in 2BC to start the 120 year first presence. That makes 6 comings. Then he came as Michael for his earthly ministry as Jesus for 3½ years, then he came again to appoint FDS2. Then he came after the first presence to remove FDS2 then he came to start his second presence in 1884Tishri. Then he came to appoint FDS3. Then he came to appoint FDS4. That makes 12 comings in all. The final coming at Armageddon is after this system ends. There are 12 in all because Jesus said:
The master of that slave will come on a day that he does not expect and in an hour that he does not know (Matthew 24:50).
You also, keep ready, because at an hour that you do not think likely the Son of man is coming (Luke 12:40).
And there are 12 hours in the day:
Jesus answered: There are 12 hours of daylight, are there not? If anyone walks in daylight he does not bump against anything, because he sees the light of this world (John 11:9).
