1. The part of speech.
Sleep is both a noun and a verb.
As a noun, it is usually uncountable (meaning 1). This is marked by a [U]. However, in meaning 3, it is countable, e.g. a deep sleep.
As a verb, it is usually intransitive (an intransitive verb doesn't have a direct object, and is marked with [I]). Meaning 2 is a special use of the word 'sleep', which is used when talking about the number of beds in a certain place, e.g. This apartment sleeps four. This is a transitive verb [T] and therefore requires an object.
