The current does not flow through the insulators. We know that a large amount of current will flow through the conductor due to the presence of free electrons. Relatively small amount of current also flow through semiconductors or some alloys. 

The given statement is false because copper is not a good conductor of electricity as compared to glass, The reason is that glass is usually an insulator and have electrons held tightly which means they aren't shared between other atoms, so it is a poor conductor of electricity whereas copper is a metal and has free electrons in it and therefore is good conductor of electricity.

The given statement is false,  because pure water is not a good conductor of electricity. Because water itself isn't a conductor. It i the presence of salts in an impure water that makes it conductive. But in pure water, it has all salts removed from it and therefore, pure water is then devoid of free ions and hence not a good conductor.

When conductors gets charged then all the charge will be distributed to the surface of conductor.

In conductors electrons can flow because their because their electrons are free and mobile.

Metallic elements have free electrons on the metallic surface and thus they are extremely good conductors. 

The materials that do not allow flow of electron through them are known as Insulators.

True

Until the overall repulsive forces between electrons is minimised, the charged particle continues to transmit charge to other particles.
