Strange Changing lights in the Eastern Sky

My wife and I live south of Watkins, Mn on a farm slightly higher in elevation than much of the surrounding area. We have seen strange lights when looking to the East, generally towards the Buffalo area. We have seen these on multiple locations all times of the year. Typically they are white to red in color and varying in intensity. Sometimes they hang out for several minutes other times it for a brief moment. Almost always they will just vanish without moving much. They will show up just above the horizon, maybe a finger or two width from our vantage point. We have seen as many as 3 of these strange lights at one time. We have had multiple friends and family that have been with us that have also witnessed these strange phenomenon. Most leave unsure of what they just saw. We moved into this place in the fall of 2019 and have seen them the whole time, the latest sighting was just a couple weeks ago on July 15th 2023. We were hanging out with a friend of ours at our grain bin bar that has a view of the eastern and south east sky. We saw these lights on and off for a couple hours. Our friend had not seen these lights before and was surprised to hear how common of an occurrence this was for us. He was so bothered by those lights that he reached out to me yesterday July 27th 2023 about it and this is what has pushed me to post this. These lights are not planes, radio towers, drones, or anything that you could reasonably use to explain it. I have seen them just after dark as well as 2:00 am, middle of summer or a cold winter night. I'm not saying I know what they are but it sure is strange.
