1. there is no electric field inside a charged conductor
2. yes it is a reality but it cant be seen in real life it can be just experienced
3. the physical quantity is electric field intensity
it is defined as force experienced per unit positive charge
E=F/q
4. electric field intensity inside a conductor is zero because there is no charge present inside the conductor as the charge resides only on the surface of the metallic conductor

The "NET" Electric field inside a "conductor" is always zero as you have said.This is basically due to the presence of a lot of free electrons in the conductor.
Let us consider a conducting plate kept in a uniform electric field perpendicular to the plane of the conductor as shown.
The electric field exerts a force F=-eE on the the free electrons of the conductor pulling the electrons to the left side ( to the direction opposite to the electric field) of the conductor creating negative charge accumulation on that side. This in-turn creates a positive charge accumulation on the other side of the conductor. This accumulation starts to create an electric field opposite in direction to the existing electric field ( that is the new electric field opposes the already existing one). This accumulation increases and so do the opposing electric field. This continues until both the electric field become equal in magnitude. So the new opposing electric field completely cancels out the already existing on (only inside the conductor). So the net electric field in inside the conductor becomes 0. All this happens basically in nano seconds. So, the conductor isn't affected by any new electric field coming across it as it is cancelled out instantly.
