When a christian woman marries a Muslim man, she has to become Muslim.
No she cannot get a scriptural divorce after she has already taken back her husband. They are "one flesh" again so if she gets a legal divorce and marries someone else, she commits adultery. If she wanted a scriptural divorce, she could've divorced him after he committed adultery and not "forgiven" him and taken him back.
There is no law preventing a Catholic marrying a non catholic.
Christian marriage is binding with only one cause for divorce. However if a Christian woman or a Christian man marries an unbeliever and they can not get along with each other they are allowed to divorce that mate.For some of the principles of marriage see I Corinthians 7:1-16.
Yes.

I have no objection.
Nothing unusual. The priest usually performs the ceremony during a Mass. The couple make the standard Christian wedding vows - love, honour, till death do us part.... and so forth. Then they sign the register.
A Catholic male or female who marries someone who is divorced, but has not received an anullment in the Catholic Church, has contracted an invalid marriage and is living in sin. While such persons are pemitted to attend services, so long as any Catholic is living in sin, the Church requires them to refrain from receiving Holy Eurcharist.
Jesus, himself, said that divorce was not correct. 'Any man who divorces his wife and marries another commits adultery. . . . '
no
If the Catholic woman marries a Orthodox man without a dispensation from the Church the marriage is ipso facto invalid, thus no annulment process needs to be begun - the marriage is plainly invalid.
