The brightness of the stars is the work of the photographer. I often ramp up the brightness levels on the stars to max in order to make them pop out more when I edit star photos.
Clouds and stars overlapping is simply the movement of the clouds and having clear sky one moment but not the next and having a ghost image.
The circle could be a satellite but honestly I see so many weird things taking photos of the stars or just laying out watching them that I wonder if more than satellites, space stations and shuttles are flying around at times.
Last year while taking photos I caught an object moving slow across many exposures. The satellites would all burn the same 2 inch or more line in the shot while this one was moving an 8th inch across the photo. It also did not have the same light pattern.
