Bright circular moving objects following each other appearing in one area moving then disappearing.

The object(s) that my mom, fiancé, and myself witnessed were multiple circular objects acting in a very unexplainable way. We were looking outside and noticed a very bright “star” or so we thought until it continued to get really bright, move forward and then slowly the light would dimmer and die out, but right before the light would completely die out, another one would appear in the exact location the first one first appeared. What was odd about this was every light would appear in the same spot before moving forward as the light dimmed off. Not all of them were the same brightness either, some were brighter then others, some would start off dim while gradually getting super bright. This was not a shooting start because it was moving upwards in direction and it was nothing that any of us have ever witnessed. This happened for 8 minuets at least from what I watched. I also have a recording of this because I honestly have never seen anything like it before. There were planes in the area as well as other stars and they were 10 times bigger in size compared to those objects in the sky. I could pick this up on my camera as with stars and planes I can’t.
