No, she can't. The line of succession, and the way to determine who is on it, has been established by law. Elizabeth can't arbitrarily change that. I suppose that she could petition Parliament to change the succession, but this would be an outrageous thing for her to do. Even with a compelling reason to do this, it would be a very serious matter, and she has no reason at all.
And, of course, Elizabeth II is not and never has been, The Queen of England.

No. Prince Phillip is a (British*) royal due to his marraige to Queen Elizabeth, and therefore holds the title of Prince Consort. However he is in no way part of the line of succession, he holds none of the powers his wife does, nor could he ever hold the title of a King.
(*He was born a part of a Danish-Greek royal family)
On King William III's Dead in 8 March 1702 Queen Anne became the monarch of England, Scotland, and Ireland.

No. You may write a letter to her, but it would be read by the Queen's secretarial staff and not by the Queen herself (unless they decide to pass it to her).
Yes Queen Elizabeth can choose to make William the King before she passes away thus by passing Prince Charles. But if she were to pass away without doing such the throne would go to Prince Charles.
The Queen cannot pass on the throne during her lifetime. The British monarchy follows a system of hereditary succession, meaning the throne passes to the next in line, typically a direct descendant or a close relative, upon the reigning monarch's death.
On the death of Queen Anne, King George [I] inherited the English throne on what might be considered a technicality. Ironically, the English government considered that the very German George from the House of Hanover, to be less of a risk than Queen Anne's half brother James Edward Stuart. So it came to pass that England had a mostly non-resident and non-English speaking king with little or no interest in England.
Nobody is absolutely sure whether Prince Charles will be King or abdicate the throne and pass it on to Prince William.
she was born a royal. and was the oldest of her siblings so, she got the job. she parents pass the job down to their children.
The heir to the throne is Prince Charles, the Price of Wales. He intends to be known as George VII.
Currently, the Heir Apparent is his Royal Highness The Prince Charles, who (if he survives) will immediately become King when Queen Elizabeth II dies. It is thought extremely unlikely that Elizabeth II will abdicate, or "step down." See the related question link below.
When she dies or becomes too ill to carry out the duties of the sole monarch on the throne. I don't think it would be "proper" for her to just retire and do her son the favor of abdicating the throne so he has more time in power. She could to that but it would be scandalous.
