From the bottom it should be below about 200m but sometimes they are 3km thick, so they can be higher. They can cover the whole sky, they have a dark grey wet look. They usually rain or snow. :D sorry too much information I guess..

No, altitude and sea level are not the same thing. Altitude is the distance of a location above sea level, while sea level is a specific level used as a reference point for measuring elevations. Sea level represents the average level of the ocean's surface.
The word you are looking for is "altitude." Altitude refers to the height or elevation above sea level.
Nimbostratus is the name of the cloud that can appear at low or mid level and appears as a heavy gray rain cloud.
Altitude is greater at a point that is higher above sea level. Altitude measures the height of a point above a reference point, such as sea level. The higher the altitude, the greater the height above that reference point.

stratus and nimbostratus
The list of cloud types groups the main genera as high (cirrus, cirro-), middle (alto-), multi-level (nimbostratus, cumulus, cumulonimbus), and low (stratus, strato-) according to the altitude level or levels at which each cloud is normally found.
Altitude describes an object's position relative to sea level. An object in a position higher than sea level would have a positive altitude, sea level would have an altitude of zero, and any object below sea level would have a negative altitude.
compared to the other clouds, no it is not. The heights of nimbostratus clouds are below 8,000 ft. (2400m.)
I believe that would be a cummulonimbus cloud, more commonly known as a storm cloud.

It is called altitude. It is typically expressed as ASL (above mean sea level, or MSL). However, it can also be specified as AGL (Above the local Ground Level).
