I believe it would be three times. According to Amendment XXII, "No person shall be elected to the office of the President more than twice" but the question is asking how many times can a person be president, not how many times can a person be elected to the office of the President. According to the same Amendment no person who has held the office of the President for "more than two years of a term to which some other person was elected President shall be elected to the office of the President more than once." It seems obvious then that if a person serves less than two years of a term to which some other person was elected President, the one election restriction above does not apply, and the person can be elected to the office of the President twice. These three periods in office do not have to be contiguous. This answer considers the full and legitimate holding of the office of the President, and doesn't take into account the situations where someone could be "Acting President" during another president's term. There is no specified limit to the number of times that could happen.
There is no legal limit on how many can run. However, it is expensive and requires a lot of effort to get on the ballot in every state and then to run a national campaign. There are only two major parties who always field a candidate. In some years a third national party has appeared and there are three major candidates. There are several minor parties that have candidates in some of the states, but never come close to electing a president. Considerably more people can run in the primaries in the hope of becoming a major party nominee. However, even running in primaries is expensive and time-consuming, so most losing candidates drop out after 2 or 3 losses.
Harold Stassen ran for US president nine times between 1948 and 1992.
Yes, the legally qualified voters who live in DC are allowed to vote for president. DC has been given three electoral votes and their electors vote along with all the electors from the states.
It is unclear in the wording of the Twenty-Second Amendment to the Constitution could run for the vice president's position for three terms. Its unclear because no one has ever attempted to do this before and it hasn't been tested in court. Its omission indicates that it would be possible to do so.

Someone has to run the nation. The president is the person of the people. Without the president, who is going to think through all of the bills passed by congress? No one. Without the president, the country would be in turmoil because without a leader, the people are nothing.

He ran for president twice-- once in 2008, and again in 2012. He won both times.
two times
but crak idot
two. John McCain and someone else
That depends on things like the position someone is being elected for and the country the election is being run in, as they have different systems. Anyone in a class of a school could run for a class president election as there would be no restrictions, whereas there would be many requirements for someone to run for president of a country.
