Your explanation is kind of abstract. It should be so that one can see that the reaction force is a force :
1) Jaw exerting force back on fist; we do see that the fist applies the force on jaw as it causes pain to it. But we do not see the way the corresponding reaction force reacts. And you pull out the law for explanation, saying it must be like that. This is why your explanation is abstract. A concrete proof of your explanation would be : “… and that is that reaction force which causes pain to the fist”. And also because you like to say something more, to put “If both the forces are equal in magnitude, equilibrium is maintained, and the 2 objects [not “the object does not move] do not move”, you should also explain clearly by saying like this “If both these 2 forces are not equal, then the jaw will not stand still, but get displaced backwards” and also “if these 2 forces are equal, but if the hardness of the jaw is less than of the one of the fist, then even the jaw does not move, but it will get cracked, broken”.
2) You put : “The jerk felt on the gun that pulls it in the backward direction exists due to the reaction force”. But how this reaction force is exerted? So, you need to explain clearly, instead of simply saying that by basing on the Newton’s law, so that one could grasp the real meaning of the reaction force, not just have an abstract idea about it.
Tentatively, you need to say something more, like : it is the expanding gas converted from the the gunpowder when ignited, that forces the bullet out at an extreme speed. It is this force that causes the reaction force – the recoil force transferred to the gun.
3) You put : “A person swimming in a forward direction pushes the water in the backward direction with his/her hands. This force applied by the person acts as the action force, which leads to the generation of a reaction force”. But the reaction force from where? You need to say more : from the water.
And you put “This pair of forces, acting together simultaneously on the person’s body and the water, causes the person to swim in the forward direction”. But if the volume of water is, say just a couple of times more than the body of the swimmer, then what will happens? The standstill of the swimmer body. So, while acting together, the water volume must be up to a magnitude so that its reaction force is greater than the one exerted by the whole body in movement of the swimmer on it.
3) Pushing the wall.
You put : “Therefore, the force responsible to move the chair is the reaction force; The motion of the chair can not exist without the existence of a force.”. But, if the person doesn’t push with hard enough force, then the chair will … not move at all. So, you need to say more, something like : the wall exerts a reaction force on the pushing hand – that is why there is a feeling of pressure, of pain on the 2 hands – and this reaction force must be greater than the one exerted by the 2 hands. If this reaction force is of a lesser, then the wall will collapse. And because this reaction force is greater than the applied force, so the chair moves backward. A clearer explanation : suppose the wall is put on wheels like the chair, so that it can move backwards and forwards, just like the chair. So, what happens when that reaction force exerted by the wall is lesser by that applied force exerted by the person? It then will move backwards; the wall moves, not the chair. And because you like to use the person sitting on a chair as example, you need to say more : as there is another force that is involved here, the friction force against the wheels …
4) …
… up to 10)
In brief, your introductory explanations to this matter are not clear-cut enough, kind of more or less abstract.
(Please note : there are certainly some errors here and there, about the physical or grammatical aspect of what I put in words, as I don’t recheck it; as my objective is just to give you an idea of what is a thorough, a clear explanation. And it’s better to have fewer examples [say 5] with clear-cut explanations, than to have many examples [say 10, like here] but with quick, superficial explanations).
