Yes, she could be. If Prince William has a daughter, she will be next in line to the throne, after him, and before William's brother, Harry.
However she will be heir apparant only, as while William lives, he could possibly give birth to a son who would supplant her on the line of succession.
Assuming William becomes king, and dies or abdicates with only female heirs, then the eldest of these will become Queen.
No. Queen Elizabeth will be Queen until her death. Once she is deceased, Prince Charles (Prince William's father) will become King. Upon the death of Prince Charles, then Prince William will become King.

Kate Middleton will become a princess when she marries Prince William. If William becomes king, Kate would then become queen. If Queen Elizabeth II abdicates the throne to Prince Harry however, Kate will remain a princess. This would seem unlikely considering William is in line to the throne before Harry.
No
Prince Charles The next in line will be Prince William and Princess Catherine(Kate)

Prince Phillip is not King because it was his wife who was the rightful heir to the throne and not him. The last consort of the rightful heir to the throne of the United Kingdom to become King in his own right was William III who ruled jointly with his wife Mary II. It will be different when Prince William becomes King. As his wife Kate Middleton will be Queen Consort.
His eldest son, William. Prince Harry his 2nd son is 3rd in line to the throne.
It will most likely be the eldest son or daughter of Prince William and Kate Middleton.
Once the Queen (Elizabeth II) dies, Prince Charles will become King, after he dies, Prince William will become King, and Kate, as his wife will become the Queen Consort (not the Queen Regent, like Elizabeth is)
Because there is nothing in Kate's birth, background or record to disbar her from being Queen. She would not need to be born noble.
If prince William does not accept then either his son will be king or there will not be any king
Neither, once a prince he can only be king. Actually, a duke is higher in Nobility Rank than a Prince. A prince's title does not change because he marries, however, once he marries, he is usually awarded a dukedom for his parents (King/Queen). As the ruler of this dukedom, he then becomes a duke. An Earl refers to chieftains set to rule a territory in a king's stead.
If you're talking about the line of succession, then if Prince William became king, but died without fathering an heir, then his brother Harry is the next in line for the throne.
