By changing the aerodynamic properties of the fuselage or wings. If you can physically interrupt the flow of air across the body of the aircraft and make it less aerodynamic than you are able to create and increase the amount of drag in flight. The 2 most common ways to increase drag in a modern aircraft is to arm the spoilers (speed brakes) or lower landing gear.
"increce" as a word does not exist.
Yes it does.

Drag is a force that acts opposite to the direction of movement of an airplane. Drag is mainly caused by air. The other forces that act on the plane while moving in the air are thrust, lift etc..
The drag of an airplane is the air resistance caused by the plane flying through air. Similar to when you pull your hand through water and feel resistance.
Flaps would increase drag increasing your speed will increase it even more
Drag effects paper airplane just as it affects anything else that moves. It is either parasitic or induced on paper airplanes. Drag may reduce a paper airplanes speed and/or range.

the force created by air resistance
The force of an airplane that opposes thrust is called drag. Drag is the resistance force that acts opposite to the direction of motion of the aircraft and is caused by the interaction of the aircraft with the surrounding air.
