The mayor of the biggest city in the country and his entourage will arrive at noon. This sentence is grammatically correct.

The major of the biggest city in the country and his entourage, will arrive at noon. This sentence is grammatically incorrect. "The mayor of the biggest city in the country and his entourage" is the complete subject and "will arrive" is the complete verb. Never separate a subject from its verb with a comma, not even if the subject is very long.
The major, of the biggest city in the country, and his entourage will arrive at noon. This sentence is grammatically incorrect. The placement of the commas is not correct. Both of the commas break up the subject. This may look similar to an appositive, which is when a phrase that identifies or describes a noun is placed directly after it, in between commas. However, the phrase inside of the commas in this sentence starts with "of" and is not a direct description of the mayor. If we wanted to place an appositive in this sentence, we might write something such as: The mayor, who just bought a new private jet, and his entourage will arrive at noon.
