Visibility is how far you can see. For example, if there was a lot of fog or a white-out blizzard, there would be very bad visibility because you can't see very far.
Cloud and fog are typically measured using visibility and cloud cover metrics. Visibility is often reported in meters or kilometers, indicating how far one can see in the presence of fog or low clouds. Cloud cover is usually expressed in oktas or percentages, indicating the fraction of the sky that is covered by clouds. Additionally, cloud height can be measured in feet or meters above ground level to provide more specific information about the cloud layers.
Cloud cover is a noun. "Expect lots of cloud cover today."

The air in a cool region underneath cloud cover will have higher humidity compared to a region with no cloud cover. Clouds can trap moisture and prevent it from evaporating, leading to higher humidity levels beneath them.

Yes, stars are always present in the night sky, but their visibility can be affected by various factors such as cloud cover, light pollution, and location.

Deserts usually have little cloud cover and humidity, both of which interfere with visibility. Most telescopes are located far from cities so there is little light pollution.
If the visibility is good, it indicates that there are no significant weather conditions affecting visibility, such as fog, rain, or snow. Generally, in such cases, the weather is likely to be clear with little to no cloud cover. However, the exact weather conditions and temperature can vary depending on the season and location.
visibility is often reduced somewhat by air pollution and high humidity.

Cloud cover does not have a temperature. It affects the rate of heating or cooling.
In aviation, "CAVU" stands for "ceiling and visibility unlimited," meaning there is no cloud below 10 000 feet and visibility is 10 statute miles or greater. Also used is the term "CAVOK," meaning no cloud below 5000 feet and visibility of 6 statute miles or greater.
