I do know about three prominent Bharatas from Hindu scriptures namely Mahabharata, Ramayana and Srimad Bhagavatam.
Bharata from Mahabharata was a son of Dushyanta and Sakunthala.
Bharata from Ramayana was a brother of Rama.
Bharata from Srimad Bhagavatam, popularly known as jada Bharata, who was a Jivan mukta.
Apart from the above three persons, are there any other prominent persons from Hindu scriptures having the name Bharata?
