Air Force One is the designation call sign for any aircraft that is carrying the President of the US. When he departs the a/c and it flys away, that a/c then flies with a different designation.
There are currently two Boeing 747 aircraft that are painted in the colors and with the Presidential seal. The one carrying the President on board is commonly referred to as Air Force One (whichever of the two plane is in service).
Air Force Two is the a/c that is carrying the Vice President.
Marine One is the helicopter that flies the president to and from the White House lawn. Again, this designation is for the helicopter while the President is on board. The Marine squadron may have more than one configured to carry the President.
During times of war, the President is transferred to an E-4 Airborne Command Post. From this a/c, the President and staff can make decisions to go to war. This a/c was depicted in the movie "Patriot Games", and it had some good interior views of the aircraft layout.
There are 3 E-4 aircraft that are used for this mission. There are 4 other E-4's that are assigned for Air Force's mission to have a flying command post. These a/c can be rotated between the different mission requirements. Whenever, the President goes outside the US on Air Force One, the E-4 Command Post stays within 200 miles of his location in case an emergency developes.
There are two virtually-identical Boeing VC-25 aircraft (modified 747s) that are in the regular presidential fleet. Technically, any aircraft may be given the flight designation "Air Force One" as long as the President is on board; it does not refer to any specific aircraft.
The President does not fly Air Force One- he flies ON Air Force One
Air Force One can typically accommodate up to 70 passengers, including the president, White House staff, Secret Service agents, and journalists. The aircraft is equipped with various amenities to support both official functions and long-distance travel for the president and accompanying personnel.
The top speed is between 630 and 700 miles (about 1,126km) per hour and the ceiling maximum (i.e how high the plane can fly) is 45,100 feet (commercial 747s fly at about 30,000 feet)
There are many Rosas out there and there is no context provided. Rosa Parks is one famous Rosa who had dealings with the Air Force. At one time she worked on an Air Force base.

Air Force One will remain Air Force One no matter who the President is.

The "famous" Air Force One, which is a Boeing 747, is the largest American-branded commercial airliner available when they let the contract - both to show American prestige, and because they really need a huge plane. (Air Force One is the plane the President is in at the time, unless the plane doesn't belong to the Air Force; the S-3 Viking that carried President Bush to the Mission Accomplished speech was named Navy One while the president was aboard. This means that Air Force One can be any airplane; President Clinton used a C-9 to travel to Fort Drum, New York, in 1993 because a 747 couldn't land at Fort Drum's airfield in 1993, and while it was in presidential service it was Air Force One.) As to the specific two planes - yes, there are two identical 747s - chosen...they were custom made for the government.
Yes, all members of the Air Force one crew are members of the United States Air Force.
Air Force One is the call sign used describe any aircraft carrying the US President, so in theory Air Force One could be any type of aircraft. The official Presidential fleet consists of two customised Boeing 747s, either of which may be colloquially referred to as Air Force One. However this only becomes the official designation when the President is on board.
"Air Force One" is a designation not the name of the plane. There is only one Air Force One and is what ever aircraft the president is on at the time. When he is on a helicopter, it's "Marine One" There are two aircraft dedicated for the president to use and they are kept at Andrews AFB just for his use. But the designation "Air Force One" is the current aircraft that he is on at any given time.
