No. At least, all available evidence seems to indicate that it is not possible to transfer matter, energy, or information faster than the speed of light.
The speed of light is not limited in a vacuum - the speed of light is fastest in a vacuum. But that is what Einstein called the "Cosmic Speed Limit" - nothing can move faster than the speed of light in a vacuum, or even quite asfast.

About 2/3 its speed in a vacuum.
The speed of light is 186,000 miles per second in a vacuum.
A "fact" is basically anything you can state, especially if such a statement is true. Since you can say "light has a speed", and since that is true, it follows that it's a fact. Light through a "vacuum" is the meaning of "the speed of light." Light through glass is slower.
No.

No, it shouldn't. And it isn't.

No, slower. Light travels fastest in a vacuum. Anything transparent that light can pass through slows it down somewhat. Diamond crystal slows it down notably, which is part of what causes the "fire" in a diamond.

We generally consider that the force of an electric field moves at the speed of light. And electricity moves at the speed of light.
The fastest that anything can go is the speed of light in a vacuum.
If you mean "normal speed" to be the speed at which light travels in a vacuum, then no. Anything that differs from light moving through a vacuum slows the light down to a certain extent.
The speed of electromagnetic radiation of all kinds, including light, is faster than the speed of anything else.
Nothing is faster than the speed of light in a vacuum (other household appliances are left as an exercise for the reader). Electricity travels at essentially the speed of light in the conductive medium it's traveling through, but not faster.
