Have you not read the Bible (the Word of God). It tells you God made the Stars and He knows all of their Names. They are Angels!....
also, the word used in Psalm 147:4 for "stars" means "stars" every one of the 37 times it is used in the Bible. it's not used to describe angels. stars.
just because in John's vision he saw angels appearing as stars ((Revelation 12:4)) doesn't mean literal stars are literal angels, or that you can go back through the Bible and replace every mention of stars with angelic beings.
