The function of a dielectric is to be the support between to conductive components. It has nothing to do with the action taking place, but buffers the area in which the action is taking place.
For an insulating material dielectric strength and dielectric loss should be respectively
The dielectric,usually the insulator between the plates of a capacitor, can be overstressed by the application of too high voltages applied to the capacitor plates. The dielectric breaks down and a current flows between the plates until,either they are discharged, or an equilibrium is reached,below the working voltage of the capacitor. If the dielectric is damaged in this process he capacitor must be replaced. Some dielectric material self heal and can recover from an over voltage.
Capacitors are named after their dielectrics. So, an 'air capacitor' uses air as its dielectric, a 'mica capacitor' uses mica as its dielectric, and so on. There are lots of different dielectric used to separate the plates of a capacitor, each with different permittivities and dielectric strengths. As the perfect dielectric (i.e. one with both a very high permittivity and a very high dielectric strength) doesn't occur, the choice of dielectric is always a compromise between it permittivity and dielectric strength.
No, these are two unrelated properties of a material.
boundary conditions for perfect dielectric materials
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.

A leaky dielectric is a poorly conducting liquid. Refer to "ELECTROHYDRODYNAMICS: The Taylor-Melcher Leaky Dielectric Model" for more information.

The dielectric breakdown strength is 3,000 volts per millimeter.
Yes possible. As a capacitor even with air as dielectric allows alternating current to pass through the capacitor filled with some material as dielectric would allow current to pass through it
