You can always paste a new sky in an mask out or erase any overlaying areas.
Sometimes you can paste in a new sky and then change your blend mode to multiply.
When adding in a new sky, be sure to make sure the color tones match the tones of the image you are putting it in. The direction of the sun also plays a huge factor

In PS you will need to use the marquee tool to trace around the image or area of what you want to copy. Then go to the other image and click on ctrl v and it should past it onto the new photo as a new layer
