No. Comic is a noun and smart is an adjective.

To determine if something is parallel, we need to understand what parallelism means. Parallelism is the repetition of grammatical form within a sentence or phrase. In your example, "My sister Aliah is both a comic and smart," the sentence does not demonstrate parallelism. This is because "a comic" and "smart" do not share the same grammatical form.
To make this sentence parallel, you could rephrase it as: "My sister Aliah is both a comic and intelligent." In this revised sentence, "a comic" and "intelligent" are parallel because they both follow the same grammatical pattern of an adjective preceding a noun.
