The top of profile is called extraback, underside intrados.

Biplane. Strictly speaking it has ONE wing on top of the other. General usage is to refer to the bit on each side of an aircraft as a wing, but technically the wing is the entire structure from tip to tip.

The larger wing was usually on the top.
The top bit of the centre is called the Northern Territory, the bottom bit is South Australia.

It is called the plus sde and the other is called the minus.
....just like all airplanes work. The prop , spun by the engine, pushed the plane forward into the relative wind. The wing splits the airflow over the top and bottom of the wing. The top of the wing is curved and the bottom is flat. The distance over the top of the wing is longer than the distance under the bottom .... thus the air has to move faster over the top than the bottom so that it reaches the trailing edge of the wing at the same time. As speed goes up, density goes down and thus the pressure under the wing is higher than that at the top and the wing is pulled up (or pushed up if you want to look at it that way). Along with the wing, goes the rest of the plane. To a degree there is also a down thrust of air from the wing and this produces a force on the wing pushing it up. One very interesting idea that the wright brothers used was called wing warping to cause their flier to bank. Rather than ailerons , their wing actually twisted a bit and that cause the aircraft to bank. On the Wright Flier, angle of attack was controlled by an elevator in front of the rest of the aircraft rather than at the tail.
It is just called the wing.
If you are referring to the distance from wing tip to wing tip, it is usually called "wingspan".
