According to Wikipedia (search Zucchetto) the origins seem to be largely practical - to keep the priests head warm in cold churches. Tradition still survives for bishops to remove the Zucchetto when coming into contact with the Blessed Sacrament (and churchgoers will see the Bishop remove the Zucchetto at the beginning of the Eucharistic prayers {more specifically, the Preface} until just before the Final Prayer) - Bishops also remove the Zucchetto for benediction, or for processions with the Blessed Sacrament, such as on Holy Thursday or on Corpus Christi).

Catholic AnswerRegardless of its orgins, the Zuchetto (the small skull cap) is part of the attire specified for Bishops, Archbishops, Cardinals, and the Pope. It is a sign of their Office and the color is different for each. An abbot, is required to wear a black Zuchetto, and priests may wear a black one, as well, but it is not specified..Catholic AnswerFor Mass the Bishop wears the same thing that a priest does: alb, stole, cincture, chausable. The only thing different on a Bishop, he would be wearing a pectoral cross, a zuchetto and a miter.
No. Because they might have diffrent religions. As an example a bishop will wear a suit and a catholic bishops will wear robes.
The Zuchetto has eight panels, while the Yarmulke has many different shapes, sizes, and patterns. And they have some difference in purpose. The original purpose of the zuchetto was to cover the tonsure, most likely for warmth in the days before central heating. It has become a symbol of tonsure, and therefore the zuchetto is proper for wear by all clerics, not just priests and prelates. The yarmulke (actually called a kippa (kee-PAH) by the majority of Jews) is a symbolic item. It is meant to be a visible acknowledgment that HaShem (The Creator) is always above us.
Normally, priests do not wear a mitre, only a bishop does. In the Eastern Catholic Churches there are mitred archpriests or chorbishops who are ordained priests that are entitled to wear a mitre.
