I saw 5 bright objects that seemed to reflect the light from the sun. Seemed slow but bizarre trajectory

I saw these lights while walking my dog during sunset. They seemed to be reflecting the sunlight rather than creating light of their own and I could no longer see them once the sun had completely set. I could not discern shapes, just brightness. They seemed to be very high in the sky. They moved with a very strange trajectory, like they were falling up and North if that makes sense. They all moved together. The blue dot next to the tree was not seen by the naked eye, but the 5 lights in the sky across my picture were visible. I don’t really buy into UFOs and aliens and all that, but I eventually thought to take a picture when I realized I could not explain what I was staring at. I have a Master’s in engineering and wanted to figure it out later, deciding that they were probably balloons of some kind. I tried to get a video of the strange movement but the window of opportunity had passed; the sun had set. I decided to submit now after learning that there was a spate of UAP sightings across the country shortly after and confirmed by the military.
