What are these "lights" in the sky in my drone picture?

I have a photo, original and unedited with some unexplained lights in the sky. Here’s an explanation on the scenario. My pics were taken March 10, 2021. I took them all using a drone, Mavic Pro with a filter for light reduction on the lens. I sent the drone up and took pics at multiple times, once around 7:30am and also around 10:30ish am and 1130ish am. This was taken in between storms that hit our area, Mission Viejo, CA. When I eventually uploaded the drone pics to my PC to do my editing is when i noticed the lights. I finished my edits on the first photo and zoomed all the way into the sky to see how much noise was there so that I knew how much noise to remove. I happened to zoom into a part of the photo where one of the lights were. I immediately removed all of my edits and went back and looked and found approx 30 of these lights. I believe there are at least 2 lights that are below the tops of the mountains as well.

I have not had the time to look through all of these photos, but i have looked through a few and the lights are in a few of the photos in the same area from different times, around 730am and 1050isham. I am calling them “lights”, however I’m not saying that’s what they are. And that’s why I’m here, to see if anyone can help, or knows anyone that can help. I have for the most part ruled out lens dust, of course i could be wrong though. Im wondering if there could be some type of meteorological explanation? Most of the lights appear in the blue sky, however some appear in some of the very thin clouds where there is also some visible blue sky behind them. Also as i mentioned, on the far left of the photo it looks as if there are also a couple of the lights below the top of the mountain.

I dont know what this site will let me post, but i should be including the original (unedited except for watermark)enter image description here, as well as a few snapshots taken from the original that are completely zoomed in with magnifier circles placed around some of the lights to zoom in more as well as to show you what you are looking for in the original.
