There is no overall maximum number of terms that someone can be President of the USA, but there is a limit of two consecutive terms. It is possible that someone could serve two terms, sit out a term, then serve two more terms.
The 22nd amendment limits presidents to a maximum term of just under 10 years. There is no corresponding limit for the vice-president; a person could theoretically be the vice-president for multiple presidents.
There's no limit on the number of times a person can run for president, though they're limited to how many times they're allowed to serve as president (two full terms). If a vice-president becomes president, it's considered a full term if they were president for more than two years and not counted if they were president for less than two years. So the maximum length of time someone could be president under current law is 10 years.
A U.S. President can serve two four-year terms, but could potentially serve for upwards of ten years by starting as Vice-President and ascending after at least two years of that term.

There is no theoretical maximum, but the practical maximum is a day less than ten years: a vice president could serve just under two years of his predecessor's term, and then two full terms of his own.

They can't but, if the president could fire the vice president, this could mean that the person who is the vice president was not the person citizens voted for in the presidential elections. First, that could cause anger amongst people who would feel cheated/betrayed. Secondly, the president could carefully select who they wanted to be vice president so that the vice president agrees with everything the president says, giving more power to the president (turning the vice president into a 'puppet leader').

Yes. The 4-year term for the office of president is part of the original Constitution. Also, there was no limit to the number of terms a person could have in the original Constitution.
Though it is not stated, a person needs to be alive to be president of the US.
