Yes he can.
No.
Members of the Church of Jesus Christ of Latter-day Saints (the "Mormon" church) are encouraged to marry others within the faith, but do not object to mixed-faith marriages. Mormons do not object to mixed-faith or mixed-race marriages.
Members of the Church of Jesus Christ of Latter-day Saints (the "Mormon" church) may marry someone outside the religion if they choose. However, most Mormons like to marry within the faith, or to marry someone who is preparing to convert, because they believe that a shared faith makes a stronger family. David Archuleta has not said if he will date or marry outside his religion or not.
Yes. There are no restrictions on Baptists, Methodist or Anglican clergy marrying.
No, not unless the previous marriage is annulled, no matter where he was married

Of course! Members of the Church of Jesus Christ of Latter-day Saints (the 'Mormon' church) can date whomever they choose. The Church does not tell people who they can and cannot date. The Church does suggest members should date those of similar high moral standards, and preferably those from the same faith, but this is not required. Most Mormons do choose to follow these guidelines because Mormonism is a very family-centered faith and it is important to them to marry and raise their children in the church.
No, for you to raise your children in the Orthodox faith, you yourself must go through the sacraments of the church. Marriage being a sacrament, you must raise marry in the Orthodox Church first before you raise your children as Orthodox.
In general, a member of the Greek Orthodox Church can remarry if their previous marriage has been dissolved by divorce or annulment. However, there may be certain restrictions or conditions depending on the circumstances and the guidance of the church authorities. It is advisable for individuals seeking a second marriage to consult with their priest or bishop for guidance and proper procedures.
For the same reason that all Catholic priests are not allowed by the Church to marry. The bible refers to the church as "the bride of Christ," and Catholicism considers its clergy "the church." Therefore, priests (and bishops) already are married -- to Christ!
In general, members of the Iglesia ni Cristo church are discouraged from marrying individuals of other religions. The church places a strong emphasis on the importance of marrying within the faith to maintain unity in beliefs and practices. However, it is ultimately up to the individual members to make decisions about their personal relationships.
== == If the church is only a setting for the wedding, almost anyone may be married in a church, generally speaking. Regarding the person who officiates, I don't know the rules in the Church of Christ, but an Adventist pastor would not be willing to perform a marriage between an Adventist and someone of another faith: in the Bible, it says to not be "unequally yoked," which for Adventists means that you shouldn't marry someone who has different beliefs. A Seventh-day Adventist pastor has to be ordained in order to be able to perform marriages. The position of the church is to marry a non-Adventist couple or an Adventist couple. Marring a non-Adventist with an Adventist is what the rule of the church does not allow. But there is the other option, civil marriage in court.
