They have to stay away from other planes so flying at different heights gives them room. Several can be "stacked".
The heights model aircraft fly is really only governed by how far their controllers can see. In theory they can fly thousand of meters high.
Of course, planes can fly.
Your monster will automatically fly at different heights, as monsters like to be free. You do not need to do anything to control it.
it can fly
No, there is too much atmospheric drag at these heights for a satellite to maintain an orbit, but it is too high for airplanes which have 'air breathing' engines. Some high altitude planes such as the SR-71 Blackbird and U2 can fly up to 25km, but not as high as 50km which is the lower boundary for the Mesosphere. Some experimental rocket planes such as the X-15 have been able reach these heights.

Design and structural flaws determine the "absolute ceiling" of any particular aircraft, which is why some can fly at higher altitudes than others.The SPACE SHUTTLE, for example, can fly at virtually unlimited heights, and it technically qualifies as an "airplane."
Some people want to travel during the day, some want to travel at night, some planes travel faster than other planes, some planes fly a short distance, some fly a long distance. Sometimes the weather effects the way planes fly.
How do heat engine allow planes to fly
Airplanes fly at different levels according to their size and noise. Smaller planes fly at the troposphere. Bigger airplanes fly on the stratosphere.
At high altitudes the atmosphere is less dense that at lower altitudes. This means that planes flying higher experience less drag (friction) than those lower down, so that means they can go faster.
At least 6 planes.Hunter,etc
