it travels faster through air.
Light travels faster through a vacuum than through any other medium, such as air, water, or glass. In a vacuum, light can travel at its maximum speed of approximately 299,792 kilometers per second.
No, microwaves cannot travel through a vacuum because they require a medium to propagate, like air or glass. A vacuum has no particles for the microwaves to interact with and therefore cannot transmit them.
Light waves can travel through a vacuum, air, water, and transparent materials like glass and plastic.
Sound travels faster through aluminum than glass because aluminum has a higher speed of sound due to its higher stiffness and density compared to glass.
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".
No, slower.

i dont know but the sound will stay more in glass
The denser the medium, the faster sound travels through it. Glass (silicon oxide) is fairly dense, and sound waves propagate through it faster than they do through air or water.
Sound travels faster through aluminum than glass because aluminum has a higher speed of sound due to its higher stiffness and density compared to glass.
Yes, that is correct. (Slower than in a vacuum.)
