Pope John II who reigned from 533-535 was the first pope to change his name. His birth name was Mercurius, the name of a Roman god. That name did not seem appropriate for the leader of the Catholic Church.
After St. Peter (Simon) no pope changed his name until the year 533 with Pope John II. His birth name was Mercurio and he did not think it proper to be named for the pagan god, Mercury. Few popes took on a regnal name until the 10th century when the practice became the norm. So, yes, there have been many popes who did not change their names. Even today, it is not a requirement and the newly elected pontiff can retain his Christian name if he so desires.
