Well, there are no personal pronouns in this sentence, so your question must be wrong.
There are two pronouns here: the words everyone and his. Everyone is the antecedent, and it can be classified as an indefinite pronoun. The pronoun his is not a personal pronoun, but rather a possessive one.
A parallel structure means that the same form of a word is used throughout a sentence, such as in: I like to eat and to drink. - as you can see here, the word like is followed by two infinitives, which makes the sentence a parallel one.
