And the person next to you says something would you hear them? Or would there be some sort of delay before you heard their voice?

Is the person next to you moving at the same speed as you? If so you'll hear him fine. If he's not moving at all then you'll never hear him, as the sound can't catch up to you.
Imagine another scenario to understand what I mean. You're on an airplane which is stationary (say it's parked at the loading gate) and you're running down the corridor of the plane. You can reach a maximum speed of 30 km/h. Now, if the plane is moving at 300 km/h and you're running up the corridor, you're moving effectively at 330 km/h. It's the same with the sound coming from your mouth. If you're moving at a speed of X, when the sound comes out of your mouth, it's moving at a speed of X + roughly 350 m/s (the speed of sound).

Depends on the circumstances. If you're in an airplane, you'll hear them just fine. That's because the air that transmits the vibrations you hear as sound is moving with you. So from your perspective relative to them, neither you, they, or the air is moving.
If you're outside in the open air somehow, maybe strapped to the outside of a rocket or missile, you probably won't hear them either. As a practical matter, the noise of the air rushing past you would be louder than any noise you could make.

It depends where you are relative to the person speaking. Let's ignore the effects of being in an airplane or the effect of wind noise. You would only be able to hear the person speaking if you are within the Mach cone formed. If you are outside this cone, then you are in a region called the zone of silence, and you will not hear the object.
The Mach cone is a cone shaped region that forms behind the supersonic object. Therefore, you will only be able to hear the person if you are behind them. If you are in front of them, no sound will propagate forward.

Yes you would without delay because he is traveling at the same speed as you are.

Sound moves in the surrounding air. Since it is all relative you would notice no effect.
When you travel faster than sound it is faster than the outside sound not inside.

not if you were moving the same speed.
