The planet you are describing matches the characteristics of Venus. Venus is nearly the same size as Earth, has no moons, and its atmosphere is mostly composed of carbon dioxide, with thick clouds of sulfuric acid.
The four main moons all look about the same brightness as seen from Earth, and they are all at about the same distance from the Earth. That means that their brightness seen from Jupiter would depend on their distances from Jupiter.
