No, a Catholic should not receive communion in anything but a Catholic Church.

Yes, but the Episcopal person will probably not be able to have a funeral in a Catholic church. The spouse of a Catholic who is not a Catholic can be buried from the Catholic Church if that person has lived a good and Christian life. It happens quite frequently.

The question, as asked, makes no sense. The Pope is the Vicar of Christ and universal bishop of the Catholic Church. In a certain sense he is the Catholic Church as he, in his person, represents Our Blessed Lord, Jesus Christ, Whose Mystical Body IS the Catholic Church.
The Catholic Church's mission is to spread its teachings and welcome all people to share in its beliefs and practices. It seeks to build a community of believers regardless of nationality, ethnicity, or background, in line with its principles of inclusivity and outreach.
ExcommunicationRoman Catholic AnswerI could be wrong, but I don't know of anyway to remove a person from the Catholic Church. If a person is a Catholic, then they remain a Catholic, subject to all the laws of the Church until they die. An excommunicated person is under a specific penalty in which they can not receive the Sacraments or be given a Christian burial, but they are still required to attend Mass, and abide by all the other regulations. A person may remove themselves from the Church's jurisdiction, but they are the only ones who may do that - the Church cannot.
