In a Propellor driven aircraft, the propellor winds it's way through the air in the same way as a Ship propellor winds through the water. If there is not much air, then the propellor has nothing to pull through and it spins fast but does not move forward very fast. At high altitude there is not much air so the plane has to fly at much lower level where there is plenty of air. Jet aircraft use the fuel to push very hard against the turbine blades and the exploding fuel thrusts against the turbine blades, and forces the plane forward as the burnt fuel leaves the plane. With jet aircraft the thin, sparse air at high altitude is not such a problem but it still needs air to cause fuel combustion. Jet planes can fly at higher altitudes. With space Rockets that power off into space where there is no air, they achieve combustion by using chemicals that contain oxygen, and the thrust of the burning fuel leaving the rocket, pushes against the rocket, and moves it forward into space toward the moon or where ever.
Stratosphere

When the aircraft is flying above supersonic speed the engine is actually producing more than 100.000 horsepower.

Most planes fly in one layer of the atmosphere called the troposphere. High flying aircraft can fly into the stratosphere
Supersonic No. The fastest ever flown was mach 3.1 by the SR-71 Blackbird
The normal flying is in the Stratosphere. A normal Boeing or Airbus may trsvel at 25,000 feet to 45,000 feet. This may differ if the plane is small one.Usually around 30,000 - 35,000 feet.

The mach number is the speed of an aircraft, expressed as a fraction of the speed of sound in the atmospheric conditions in which the aircraft is flying. An aircraft flying at mach 1 is flying at the speed of sound.

It really depends at what latitude the flight is operating. The lowest layer of the atmosphere, the troposphere, extends up to an altitude of about 23,000 feet (7km) at the poles, and an altitude of about 60,000 feet (17km) at the equator. Therefore, at the poles the aircraft would be flying above the troposhere, in the stratosphere. At the equator, though, the airplane would still be in the troposphere. As you go north or south from the equator, the maximum height of the troposhere (known as the tropopause) generally decreases from 17km to 7km. However, there are notable 'step' changes in the height of the tropopause, where there is a large change in temperature. This causes the high speed winds known as jetstreams, which aeroplanes use to improve journey times. At any location, the height of the tropopause (i.e. depth of the troposphere) is a function of temperature and air pressure/density. As it is warmer and pressure is lower at the equator, the tropopause is higher here than at the poles.
