Final answer:
The pronouns in the sentences are being used as subject, predicate nominative, and appositive.
Step-by-step explanation:
In sentence 1, the pronoun 'He' is being used as a subject pronoun, as it is the subject of the sentence. The sentence can be rewritten as 'He and Bev are using the new computer.'
In sentence 2, the pronoun 'he' is being used as a predicate nominative, as it renames the subject 'Toni'. The sentence can be rewritten as 'The dancers on the floor are Toni and he.'
In sentence 3, the pronoun 'We' is being used as a subject pronoun, as it is the subject of the sentence. The sentence can be rewritten as 'We language specialists thoroughly enjoy our jobs.'
