These are examples of "noun phrases", which is a phrase that performs the same grammatical function as a noun in a sentence, generally as a subject, object or prepositional object. It generally consists of a noun or nouns and adjectives and adverbs that modify or describe those nouns and themselves.
For example "the very hungry caterpillar" and "some wildly popular entertainers" are examples of noun phrases.
As a general rule/guideline, if a whole phrase can be replaced in a sentence with a pronoun (in the same way that a noun can be) then that phrase is a noun phrase.
For example, in the sentence "The very hungry caterpillar ate the leaf," the noun phrase can be replaced with the pronoun "it" resulting in "It ate the leaf".
