1. From classical theory, light is electromagnetic waves in nature. The reflection of light can be explained by absorption and re-emission of electromagnetic waves, which has no relation with action-and-reaction.
2. Sound waves progpagate due to vibration of air molecules. The vibrations are transmitted through molecular interaction by intermolecular force, which is electromagnetic in nature. Likewise, the reflection of sound invloves electromagnetic interaction of air molecules and the molecules of the reflecting medium. You can't simply apply action-reaction process to describe this phenomenon.
3. Any interaction between molecules is electromagentic in nature. The answer to Q2 still applies.
4. Action and reaction forces are always equal in magnitude. The breaking of the stone is just a RESULT of the application of the action force. You feel the reaction force before the stone is broken.
5. You see the light bulb because there are scattered light inside the room. Should there be no light scattered (e.g. in an open space in a complete darkness night), you could only see a bright spot but not the whole bulb.
