Yes, "cloud" can function as a preposition when used in phrases like "in the cloud" or "above the cloud." In these cases, it shows the relationship between an object and its location in relation to the cloud.
Cloud base refers to the altitude above the ground at which the lowest portion of a cloud is observed. Cloud ceiling, on the other hand, is the height above the ground of the lowest cloud layer covering more than half of the sky. Cloud base is the specific altitude at which a cloud starts, while cloud ceiling is the overall height of the lowest cloud layer in the sky.
Cirrus clouds are the highest cloud. They are 6 to 8 miles above ground.

Yes, a white cloud above another cloud is likely composed of condensed water vapor and small ice crystals. As warm, moist air rises, it cools and condenses to form clouds. The white appearance is due to the scattering of sunlight by the tiny water droplets and ice crystals within the cloud.
