Why were some of their names changed?
This is from the Q&A in Catholic Answers (http://www.catholic.com/thisrock/quickquestions/keyword/New%20Testament/page6)
Jesus changed Simon's name to Peter as a way of signifying the special role he would play in the Church.
Saul/Paul's name was never really changed. Saul was born a Jew (his mother was Jewish) and his Hebrew name was Saul, but his father was a Roman citizen so Saul also had the Latin name Paul, having dual names was common in those days. When he brought the gospel to the Gentiles he used his Roman name.
