We seen up to 7 oval lights in the sky

I'm Siro Saracino, professor of piano in Italy and owner of some properties in US. I was on my property in Dateland with a friend when it was 9:32 pm. We had seen light up like a very strong oval light in the sky, on the horizon above Dateland, to the west, in Yuma direction. Shortly after, another light comes on, always oval and then gradually others, up to 7 objects. While the others lit up, the previous ones turned off and others lit up at various points and directions. Some were in pairs and some were single, and one of them moved quickly from right to left. The color of lights was orange, like a fire and they were very bright. Lights left no trails. Everything lasted more than half an hour and I was able to take lots of photos and lots of videos.
