Roman Catholic Answer: That depends on the sacrament:
Baptism: normally a priest or deacon, but in an emergency may be anyone, even a non-baptised person may baptise if he intends to do what the Church does.
Confirmation: normally a Bishop, but may be a priest under certain circumstances.
Eucharist: must be a priest or a Bishop, although a Deacon, acolyte, or extraordinary minister may assist with distributing Holy Communion.
Penance (Confession): must be a priest or Bishop
Holy Orders: must be a Bishop
Matrimony: The two people getting married: must be a man and a woman
Anointing of the Sick: must be a priest or a Bishop; personally, I do not know if a deacon can do this.

Yes.
Catholic & Orthodox follow the 7 Sacraments (though in Catholicism a person may only take at the most, 6 Sacraments). Protestants do not have all 7 Sacraments.
Holy Orders is the sacrament through which a man is ordained as a deacon, priest, or bishop by the laying on of hands and prayer. This sacrament conveys a special grace and power to serve the Church and administer the other sacraments. It is one of the seven sacraments recognized by the Roman Catholic Church.

Yes, a priest can administer the sacraments even if he is in a state of mortal sin; however, this raises significant theological and moral concerns. The validity of the sacraments is not dependent on the personal holiness of the priest, as they act in the person of Christ. Nonetheless, it is expected that priests strive for holiness and seek reconciliation to fulfill their role more faithfully. The Church emphasizes the importance of a priest's relationship with God and his moral integrity in his ministry.
Both sacraments require a Priest to administer them. You receive Penance before Holy Communion. The primary requirement is your Baptism.
Roman Catholic AnswerA bishop may administer all of the sacraments and is the ordinary minister for all of them. A priest is incapable of ordaining and may only confirm with the permission of his bishop. A deacon may baptise, and witness marriage.
Roman Catholicism recognizes 7 sacraments.
The Orthodox Church also celebrates the seven sacraments. Some Protestant denominations celebrate some of the sacraments but not all seven.
Yes, because married deacons, priests and bishops are mentioned in the Bible. (1Timothy 3:1-13).
The clergy could administer the sacraments, so everyone who hoped to gain salvation depended on clergy to help them.
