All three are mentioned by name by the Apostle Paul.   Aristarchus is mentioned in Acts 19:29, Colossians 4:10 and Philemon 24. He was bishop of Apamea in Syria; St Paul calls him 'my fellow-prisoner' and 'my fellow-laborer'.   Pudens is mentioned in 2 Timothy 4:21. He was a prominent Roman citizen who gave refuge to Christians; his house was first a place of refuge for the Apostles, then one of the first churches in Rome.   Trophimus is mentioned with Pudens in 2 Timothy 4:21, and in Acts 21:29, where we learn that he was from Ephesus. He accompanied the Apostle Paul on some of his missions.   All three, like St Paul, were beheaded during Nero's persecutions.
