I think I understand what you're asking Janet (let me know if it's not). You've already named the 12 Apostles, which was the official name given to the Disciples. They were also known as the 'inner twelve' the rest didn't figure much except as bit players. Matthias was the one that replaced Judas Iscariot (Acts1:15-26), but he didn't write Matthew's Gospel. In fact nobody really knows who the author was, but it has been attributed to Matthew (Levi) himself, Apostle and one-time tax collector.

The Apostle Paul was given a different commision - to be a missionery to the Gentiles, so he spent most of his time travelling round the Mediterranean, getting into some very sticky situations, which included falling out with everybody else!
