At Revelation 1:20 it talks of the 7 Stars Being ANGELS of the 7 Churches and the Churches being represented?

I don't understand what you're saying in the least, but the reference in the bible has nothing to do with stars or constelations. The word "Angel" means messenger. All seven of those churches were in existence at the time the letter was put out to them. The "angels" are what we would call today "Pastors". It was sent to them as a letter to read directly from God Himself.
