The below list is from Wikipedia and lists only those popes recognized as such by the Catholic Church. There is also Pope Elect Stephen II who died of a stroke a few days after election. He was a priest and died before he could be ordained as a bishop. Therefore he is not included in the official list of popes.

1. Urban VII (September 15–September 27, 1590): reigned for 13 calendar days, died before consecration.
2. Boniface VI (April, 896): reigned for 16 calendar days
3. Celestine IV (October 25–November 10, 1241):reigned for 17 calendar days, died before consecration.
4. Theodore II (December, 897): reigned for 20 calendar days
5. Sisinnius (January 15–February 4, 708): reigned for 21 calendar days
6. Marcellus II (April 9–May 1, 1555): reigned for 22 calendar days

Answer 3

Urban VII (15-27 September 1590): reigned for 13 calendar days and died before coronation. This was the shortest reigning pontiff.

Pope Stephen was once considered as the shortest reigning pope (3 days) but was removed from the list of popes a few years ago as he died before being installed as pope. He needed to be ordained a priest and then ordained as a bishop before he could take the office of pope. He died before he could be ordained.
