"air", "water" "glass" - generically a medium.
Through water
Light can travel through anything. The amount of light that gets through the material will vary depending on the amount of atoms in the target material.
Light travels slower through denser media, so it travels faster through water than through a diamond.
It is not. The speed of light in any material is inversely proportional to the refractive index of that material. The refractive index of glass depends on the glass and so the speed of light varies between 156 and 204 million metres per second. By contrast, the speed of light in vacuum is nearly 300 million metres per second.Even in pure water ice, light travels at nearly 229 million metres per second. So there is no evidence whatsoever to support the question's claim of "fastest through glass".
Yes, through some materials. It certainly travels through air, and you may have noticed that it travels through water and glass.Yes, through some materials.

true, it does bend when it travles through water.

The speed of light is different in different media; light travels more slowly in water than it does in air, for example.
The speed of light is dependent on the medium it travels through. Light travels fastest in a vacuum than in water or air.
water is a medium through which light travels. water does abosrb a verysmall amount of light though

No, light does not speed up in water, it slows down.
The speed of light, which is about 300,000,000 m/s, can be affected by the material that it is travelling through. Mediums such as air, glass, and water can slow light down. For example, in water, light travels at a speed of about 200,249,000m/s; in ammonia gas, it travels at 221,200,000m/s; and in ethanol, it travels 220,400,000m/s.
