Probably not, but he can if he wants to.
When Prince Charles becomes King, his royal insignia will likely be "C" for Charles and "R" for Rex, which is Latin for King. This would make his monogram "CR." However, he has the option to choose a different regnal name, which could affect the initials used in his insignia. If he decides to use a different name, the insignia would change accordingly.
I am not quite sure but I think IF Charles keeps his name as Charles it would be C.R for Charles Rex, Latin for King Charles with an III in the middle. However, apparently he will change his name to George meaning they will be G.R for George Rex with a VII for 7th as he would be Charles 7th
Most likely Charles will become Charles III although there have been some rumors that he might take the name George VII. Of course he can take any name he wishes when and if he becomes King.
No. Although last names are not normally used in royalty, the Queen and Prince Philip decided to give their children the name Mountbatten-Windsor, so it will still be the House of Windsor.
The Cavalier King Charles Spaniel received its name from King Charles II.
Automatically. The first King with a particular name has, during his lifetime, no number. After that, the official title becomes, for example, 'Henry, eighth of that name, King of England... ' and so on with the full list of titles. Not even a King Chan choose his own number. Simply by adding one to the last king of the same name. For instance, if Prince Charles were to take that name, he would be Charles III, and subsequently his son Prince William would be William V. [In fact, Charles has let it be known that he will not assume the title of Charles III].
, this one is a very difficult one as the answer will not yet be known, it has been said that Charles may use a different name as king, but if he does continue to use Charles as his name then the initials would be C.R, which means Charles Reginier C.R. would stand for Charles Rex (King Charles), just as E.R. stands for Elizabeth Regina (Queen Elizabeth), with the Latin II for two between the two letters.
