I kind of don't get it. If I am inside of a flying supersonic airjet, will I hear my own voice or my companion sitting next to me?

yes, you will hear your voice, and your friend's voice, because the air inside the aircraft moves along with you - it does not matter what spee the aircarft is flying with.
More interestingly, contrary to the comon belief, you will also hear the sound of airplane's motors, even if they are behind you. That is because the sound can travel to you on only in the air, but also in the body of the airplaine. The speed of sound in metal is much more than that in the air, but.... that doesn't matter - you'd hear the sound even if the plane's speed was greater than speed of sound in metal - the reason, again, is that the body of the plane is moving together with you.

Yes. The speed of the sound waves relative to you and your listener will be the same as though you were not moving.
The doppler effect isn't heard by people on an ambulance moving at 100 km/h, only observers that are getting further away from the ambulance. Similarly, if you drop a ball on a plane, it won't fly to the back of the plane.

Whatever speed the jet goes, you would still hear the voice. Its the same with a fly flying inside a plane. It can still fly without being hit to the plane's wall.
