Glass is almost completely made of silica (silicon dioxide), the naturally occurring form of the element silicon. This is basically the same substance as quartz and common sand. Silica is the most abundant substance on Earth and is paradoxically a liquid.
yes
E-glass is a glass made of alumino-borosilicate, and contains less than 1 percent alkali oxides. It's most used in glass fiber.
Glass is mostly made of silica (SiO2). Silica is molecule, not an element, but in that case the most abundant element is oxygen, being that there are 2 oxygen atoms (O) to every 1 silicon atom (Si).
Gorrila glass is a "Corning" manufacturing product. It is a alkali-aluminosilicate sheet of glass. Basically, it is meant to be highly thin and resistant to much surface damage. It is mostly chemical strengthened glass.

Seeded Glass has pinhead sized bubbles. The glass softens the light coming from the bulb inside and replicates the naturally seeded glass made in colonial times.

That would be silicon, or SiO2
Because they are extremely reactive to any moisture in the air.See the Related Questions about the reactivity of the alkali metals (rubidium and cesium are the most reactive of the alkali metals).
