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.
Saint Faustina did not perform miracles. She did receive a message of mercy from the Lord, asking her to spread mercy.
No believer nor any saint has the power to perform miracles. However, sometimes God chooses to perform a miracle through the intercession of a saint or believer.

While there are stories and legends of miracles associated with Saint Thomas Aquinas, they have not been verified or confirmed by the church. As a Catholic theologian and philosopher, Aquinas is best known for his intellectual contributions to the Church rather than acts of miracles.
First of all, saints can not perform any miracles, only God has the power to do that. Saints can only intercede for us and request a miracle from God. In the early days of the canonization process miracles were not yet a part of the process. If Margaret was responsible for any miracles they are apparently not recorded.
Saint Sophia lived during Roman times. Unfortunately, very little information has survived about the early saints, simply because the documents have deteriorated over time. We know she is a saint, and to become recognized as a saint she must have met several requirements, including miracles. The lack of documentation does not mean she has no miracles attributed to her, it just means none of the documentation has survived.
If St. George performed any miracles, there is no record of them.
