Yes, Saint Peter was the pope at the time.
He was canonized in 1083 A.D by Pope Gregory
Pope Saint Stephen I apparently died of natural causes although he was listed as a martyr for many years. The Depositio episcoporum of 354 speaks of Pope Stephen I as not a martyr and he is not celebrated as such by the Catholic Church.
Pope St. Stephen I is the patron saint of Fiano Romano, Italy, only. By the way, he is the pope who ordered priests to wear vestments when saying mass and not to wear street clothes for liturgies. Also, they were not to wear their vestments on the street as everyday clothing.
Pope Saint Stephen I served as Bishop of Rome from 12 May 254 to 2 August 257. So, only one, I think!That was the first, but there have been at least 9:Pope Stephen I (died 257), Bishop of Rome from 254-257Pope-elect Stephen (died 752), elected Pope but died before being ordainedPope Stephen II (died 757), pope from 752-757Pope Stephen III (720-772), pope from 768-772Pope Stephen IV (died 817), pope from 816-817Pope Stephen V (died 891), pope from 885-891Pope Stephen VI (died 897), pope from 896-897Pope Stephen VII (died 931), pope from 929-931Pope Stephen VIII (died 942), German, pope from 939-942Pope Stephen IX (c. 1020-1058), pope from 1057-1058
