No.
I assume by Queens you mean Queens who inherited the throne and did not marry into it. 6 (7 if you count Matilda, but she was not officially recognised as Queen).
Queens, like kings were expected to marry so that they can have children who will become the next king or queen. Queen Elizabeth I never married and never had any children which led to the throne being offered to King James VI of Scotland, when Elizabeth I died, he then became King James I of England.
Yes, but he or she will need to convert to join the Church of England.
Edward 8th, who abdicated the throne so that he could marry Wallis Simpson, whom he loved, but was considered unsuitable to be queen.
Not unless you have the following criteria: You live in England, You are in the line of royalty or marry a person in the line of royalty. Tough is it not? Not just England has a royal family.... If you want to be queen you should marry an heir to the throne of one of the countries with a monarchy.
Um... If it was before Prince William I think no one.

The British Royal Family is Church of England, with Queen Elizabeth II being the "Supreme Governor of the Church of England". Catholics, or anyone who marries a Catholic, cannot be in line for succession to the throne. Prince Harry most definitely does not have to marry a Catholic.
No, you have to marry to get a visa.
She can, if a prince wants to marry her. (He might have to give up the throne to marry her.)
Yes Mary of Scotland was a threat to Elizabeth because Mary was a catholic the catholic people wanted Mary to be queen of England so England can become a catholic country . Also Mary of Scotland was a successful queen and she provided heir to he throne whilst Elizabeth refused to marry and provide heirs to the throne
No catholic queen can sit on the royal throne, the king will have to vacate the throne. We saw King Edward do it after he married Mrs Simpson.
