Starting from the top image, this JPG looks similar to the second photo (PNG) but, however, there's little edges coming from the sky. They both may look the same in quality but the difference is there with pixels. As for the last image, the GIF has more blur on the sky. So far, they all look similar with color and size. I could say the GIF has more compression with low quality.
