Do all action-reaction forces produce motion?
Some do and some don't. In the case of someone sitting on a chair, they exert a downward force on the chair due to their weight. The chair exerts an equal and opposite reaction force on them but, since this upward force acting on the person is equal to their weight, the net force is zero and the person does not accelerate. However, consider now if the person pushed themselves up off the chair with their hands. They are now exerting an additional force on the chair with their arms along with the force due to their weight. The chair will exert a reaction force on the person that is equal and opposite to the combined downward force due to the person's weight and their arms pushing. Since it is equal to the weight plus the pushing force of the arms, it will be greater than the downward force on the person due to their weight and a net upward force will be produced, accelerating the person upwards.

Can you push a wheel chair with one arm?
I've never seen a one-armed wheelchair. If one of the arms has fallen off, I'd return it for a new one or seek to have it repaired. If you are asking whether a wheelchair can be pushed using only one hand, I'd say yes, you can, if you wish to spin the chair around one wheel and aren't interested in moving the patient forward. If you wish to move the chair forward, however, then you must apply a force to the back of the chair between the two handles.
