Sorry, I knew that I answered a litte to quickly. Thank You for your help again.

You're very welcome. You're doing great!

You are correct, none of the words you listed - "he," "was," "then," "awakened," "and," and "extubated" - are nouns or pronouns. In the sentence you provided, "He was then awakened and extubated," "he" is a pronoun referring to a specific person, "was" is a form of the verb "to be" indicating a past action, "then" is an adverb indicating the sequence of events, "awakened" is a past participle of the verb "to awaken," and "extubated" is a past participle of the verb "to extubate." These words serve different grammatical functions in the sentence, such as subject, verb, adverb, and complement.
