The verse used is Rev. 12:4, but the context takes place in the midst of the great tribulation and not before Adam sinned. Daniel 8:10 seems to confirm that the stars that the dragon flung down were good angels, as he trampled them. Those are the only 2 verses in the Bible dealing with this question that I can find and both infer that the 'stars' were enemies of the dragon not his fellow angels. Is there something that i am missing here?
Your assertion that the emergence of the woman in 12:1 takes place during the tribulation does not appear to be correct, in light of these two verses taken together;
Revelation 1:19 KJV Write the things which thou hast seen, and the things which are, and the things which shall be hereafter;
According to this scripture, the Revelation is divided into three distinct sections. Those three are; the things you have seen, those that are, and those yet to come.
Revelation 11:19 KJV And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.
notice that the command to write states have seen, which designates writing at a future date and not at the present; otherwise it would say what you see rather than have seen.
In verse 11:19 begins the opening of visions of the past. Verse 19 comes at the end of the seventh trumpet judgment.
Revelation 11:15 through 18 And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever. And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God, Saying, We give thee thanks, O Lord God Almighty, which art, and wast, and art to come; because thou hast taken to thee thy great power, and hast reigned. And the nations were angry, and thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth.
beginning with the vision: in 12:1 what we have is a summary of the charges against Satan and the fallen angels all of which took place prior to creation. We know this because;
Revelation 12:17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
These events are referred to in the past tense. notice and went to make war with her seed, and not will go. We have further evidence that these events are in the past due to:
Luke 10:18 And he said unto them, I beheld Satan as lightning fall from heaven.
These words of Jesus were uttered 2000 years ago and if it was past then it was surely past when John had his vision.
The Revelation is difficult to understand unless we include the rest of the Bible in discerning what Jesus said.
Hope this helps.
