Would the word "limelight" be considered as an adjective or a noun? it says "He believes that a person can be in the limelight merely by being a good listener." I think it's a noun but i just want to make sure before i fail.
Yes. "Limelight" is a noun. Dictionaries give the part of speech of all entries. Some words can be used as more than one part of speech, but "limelight" is only a noun.
A big clue in your sentence is that "limelight" is the object of the preposition "in." Prepositional phrases, like "in the limelight," always end in a noun or pronoun.
