Ideally speaking, the ratio of the sines of the angles of incidence and refraction will be the same if the medium is the same. So the refractive index will be 1.
However, refractive index is, again, a relative value. If we say that the refractive index of glass is 1.5, it implies that the refractive index of glass, with respect to air is 1.5. So the value might change based on the media involved in refraction.
It can also be safely concluded, without much Physics, that any multiplicative quantity for the standard element will be 1. (ex: speed of sound is Mach 1)
"The refractive index of water is 4 / 3" means the refractive index of water with respect to air. "The refractive index of glass is 3 /2" means the refractive index of glass with respect to air. You change the question as ," what is the refractive index of glass with respect to water? The answer is it is the ratio of refractive index of of glass with respect to air to the refractive index of water with respect to air =( 3/2) divided by( 4/3) = 1.125
Each substance has an index of refraction. The index of refraction of water is about 1.3330 . The index of refraction of air at standard conditions is about 1.0003 . There is no such thing as the index of refraction of "water to air".
Actually we define refractive index with respect to a standard medium. Air has been taken as that standard. Hence refractive index of air is 1 and that of water is 1.33. But refractive index of water with respect to glass is 1.33/1.5 = 0.887 So, the answer is "water".
When light passes from one substance to another, and both have the same refractive index, then there will be no refraction - or change of direction - at the border. It is as if there were only one substance.
Yes refractive index of the material of the medium [glass] with respect to air is high for violet and low for red.

It's 1.0002926 with standard pressure.
Yes refractive index of the material of the medium [glass] with respect to air is high for violet and low for red.
refractive index of glass is higher than refractive index of glass slab OR density of air is less than density of glass
Fog is made out of water droplets in suspension in the air. The refractive index of these droplets is 1.3330. However the body of fog as seen on mass is opaque (enough of it will stop light) and opaque substances do not have a refractive index.
