How many different people in the New Testament are called or claim to be "Brothers" or "Sisters" of Jesus?

Regardless of the doctrine of the Perpetual Virginity of Mary acknowledged as dogma by most Christians, which would necessitate a different interpretation of the words "brother" and "sister", who all is referred to in the Bible as Jesus' brother or sister and how many people would that have been, in total, had they all been children of St. Joseph and the Blessed Virgin Mary? Does anybody actually claim to be a brother or sister by virtue of being children of either Joseph or Mary?
