the stranger, the disgruntled and the agent provocateur

Hello, teachers. Am I correct that in the boldfaced part, the stranger and the agent provocateur are single nouns, while the disgruntled is a plural noun?

We are talking about general types, so I suppose you could say those terms include everybody in those categories.

Yes, but in grammatical terms, the disgruntled refers to an entire category of people collectively, and would take a plural verb, unlike the other two, right?

No, I meant it as the subject of a verb not the object. E.g.: The disgruntled are taking to the streets of London.
