From the structure of your question, we can tell that when you say "accelerating",
you mean "speeding up", although that's only one kind of acceleration.
Assuming that's what you mean, then the answer is: Of course!
Haven't you ever started to move away from a traffic light after it turned green, and
been overtaken and passed by a car that came up behind you, never slowed down,
and sailed right past you at a constant speed through the intersection as you were
picking up speed ?

No. An object is accelerating if it is changing speed or direction of travel. Since the person in question is running at a constant speed in a straight line, they are not accelerating.
No, a body moving at a constant speed cannot be accelerating. Acceleration is defined as a change in velocity over time, so if the speed of the body remains constant, there is no acceleration. For example, a car moving at a steady 60 mph on a straight road is not accelerating.
If an object is not accelerating, then one knows for sure that it is moving at a constant speed.
No, an object moving at a constant speed cannot be accelerating. Acceleration is defined as a change in velocity over time, so if the speed is constant, there is no change in velocity and therefore no acceleration.

If the force acting upon an object are balanced then the object must not be accelerating
Yes. The simplest example is an object moving at a constant speed in a circle.
Not accelerating. It could be stationary or moving at a constant speed.
Not possible, acceleration dV/dt =0.
No. 'Acceleration' means a change in speed or direction over time. If the car is moving at a constant speed in a constant direction, then it isn't accelerating.
You are most aware of motion in a moving vehicle when it is accelerating, as you can feel the change in speed more distinctly. When the vehicle is moving steadily in a straight line, the sensation of motion becomes less noticeable because your body has adapted to the constant speed.
Acceleration refers to a change in velocity, which can occur even if the speed remains constant. For example, if an object is moving in a circular path at a constant speed, it is still accelerating because its direction is changing constantly. So, it is possible to be accelerating and traveling at a constant speed at the same time.
