There have been two miracles attributes the Pop John Paul the Second. The first was a healing of a French nun from Parkinson’s disease. The second was miracle attributed him that was confirmed by Pope Francis and this is his canonization.
Two, actually. If the Pope finds that you did in fact make those miracles, he will proclaim you a saint.
Two miracles attributed to Pope John Paul II were the healing of a French nun, Sister Marie Simon-Pierre, from Parkinson's disease in 2005 and the healing of a Costa Rican woman, Floribeth Mora, from a brain aneurysm in 2011. These miracles were cited as evidence for his canonization as a saint in the Catholic Church.
The official canonization process was not in place at the time that Patrick was declared a saint. No miracles were required.
At the time of Lucy's death, there was no canonization process so no miracles were required. She was declared a saint by the local Christian community based on her martyrdom.
Each individual case is based on its own merits. Usually 2 miracles are required, one for beatification and one for canonization. If the person died as a martyr, one or more miracles may be dropped. Other things can also be taken into consideration such as bilocation. incorruptibility, stigmata, heavenly perfume, etc.
Canonization, the process in which the Pope declares someone a saint, or "raises him to the altar", worthy of veneration, and you may ask his intercession before God. It means that the person lived an exemplary life, died a holy death, and that it has been proved that there are two miracles directly attributable to his intercession.

St. Agnes is a "pre-congregational" saint. She was declared a saint before the Sacred Congregation for the Causes of Saints came into being that required Rome to examine all evidence before a person could be declared a saint. Except for unproven legends, there is no written record of any miracles that could be attributed to the intercession of St. Agnes. When Agnes was proclaimed a saint, there was no official requirement that miracles be proven.
Two years after her death (August 11th, 1253) Pope Alexander IV canonized her (1255).
Generally, two miracles are now required before a candidate can be canonized. In extraordinary circumstances, such as martyrdom, only one miracle may be required.
Miracles were not required for declaring a person a saint in the early years of Chrisitianity. The person would have been declared a saint by popular acclamation to a bishop based on the lives and merits of the candidate. This was especially true if the person died the death of a martyr as it was felt that making this ultimate sacrifice for Our Lord would be an automatic designation of that person as a saint. Even today, miracles are not always a requirement for canonization, especially in the case of martyrs.
Canonization is the declaration by the Pope that a deceased person is raised to the full honors of the altar, i.e., a saint after previously having been beatified. Two miracles credited to the beatus (feminine: beata) are usually required before canonization to attest the heroic virtue of the saint. - from Modern Catholic Dictionary by Fr. John A. Hardon, S.J.
