Do all colors refract at the same angle when entering a medium?

No, the fact of the rainbow demonstrates that the different wavelengths refract at different angles. If they didn't then the rainbow would be all one colour.

When light rays enter a medium at an angle they?
The light rays will refract towards the normal of the medium and emerge out at the same angle.
What refract means?
It means that light changes its direction when it passes from one medium to another - for example, from air to water.
What angle of waves do not bend when entering a new medium?
sharp angle
How does critical angle depend on color of light?
Critical angle of a medium depends on refractive index of the medium. Different colors of light have different wavelengths have different refractive indices.
What will a wave entering a new medium at an angle undergo?
Refraction.(I'm giving you a pass on the wording of the question. A wave always crosses theboundary between two media at some angle. The angle really should have beendescribed in better detail.)

How do light refract?
when light travels from rarer medium(which has relatively lower density) to a denser medium(which is of relatively higher density) the angle of incident light and refracted light is less than 180 degree(when the angle is considered at the point of incidence) and when the light travels from a denser to a rarer medium the angle will be greater than 180 degree.
How is light refracted when the angle of incidence was 0?
One possibility is that the medium the light is supposed to refract from is a metamaterial, an artificially created material with a negative refractive index.
How does critical angle depend on color of light?
Critical angle of a medium depends on refractive index of the medium. Different colors of light have different wavelengths have different refractive indices.
What behavior describes two sides of a wave moving at different speeds upon entering a medium at an angle?
Refraction.
What do we use to refract light?
A transparent/translucent medium with a density that is different to the one it has just left is necessary to diffract light. For example, you could shine light into a block of glass to diffract it at a different angle to when it entered.

Does the principle of optical reversibility hold for reflection as well as refraction?
Here's the way I see it: Optical reversibility means that if a light passes through a medium with an index of refraction, n, and the light hits that medium at a certain angle, the angle of incidence, the light refracts and comes out at a different angle than the angle of incidence. In other words, if light hits a refracting medium at 10 degrees to the normal, it will refract and come out at 7 degrees to the normal. Then, if it were switched, and the light were made to hit the refracting medium at 7 degrees to the normal, then it would refract and come out at 10 degrees to the normal. This is optical reversibility as seen in refraction. In reflection, however, the angle of incidence and the angle of reflection is the same. If light hits a reflecting medium at 10 degrees, it will reflect at an angle of 10 degrees. So if the angles were switched in this case, it would do nothing, it would just hit the reflecting medium at 10 degrees and again be reflected at 10 degrees. So, does the principle of optical reversibility hold for reflection as well as refraction? It depends on if you view switching the position of the same number to be reversing anything or not. Actually the principle holds good for every optical system in geometric optics....
When do you have critical angle?
A critical angle refers to the highest angle the light can possibly refract into or between objects without disappearing. ie = light going from crystal into water, the critical angle is 47degrees.
Why does a prism break down white light into all the rainbow colors?
Light refracts(bends) when it passes through to a different medium at an angle. White light is a mix of all the colours of the rainbow, and each colour has it's own refractive index, which means it bends to a greater or lesser degree compared to any other colour. Refracting white light refracts all the colours, but they all bend to different degrees, so they split up.
