The superlative form of "forth" is not commonly used because "forth" is an adverb that indicates direction or movement and does not have comparative or superlative forms like adjectives do. However, if you are looking for a way to express the idea of being the most forward or advanced in a context, you might consider using phrases like "most forward" instead.
The comparative form of "forth" is "further," and the superlative form is "furthest." These forms are used to compare the degree or extent to which something is done or exists in relation to others. In this case, "forth" is being compared to other distances or extents.

It is interesting ( to those who find it interesting) that English lacks a form expressing diminishment of adjectives. We have comparative and superlative forms in which the meaning of an adjective is augmented e.g. small, smaller, smallest; but no "diminutive comparatives," e.g. "big, less big, least big." So depending upon the context, the antonym of "superlative" might be lowest, most inferior, worst and so forth.
Sleep is a noun and does not have a superlative. Sleepy is an adjective and the superlative is "sleepiest."
