I'm not sure
Not necessarily. Two bodies co-orbiting can have different velocities depending on their mass and distance from the central body. The velocities of the bodies would be determined by the balance between gravitational force and centripetal force.
The final velocities of the gliders after a perfectly elastic collision will also be equal and opposite to their initial velocities. This is due to the conservation of momentum and kinetic energy in elastic collisions.
Two objects with different velocities can have the same momentum if one object has a greater mass and a lower velocity while the other object has a lower mass and a greater velocity. Because momentum is the product of mass and velocity, if the product of mass and velocity for each object is the same, their momenta will be equal.
The diagram you are asking for looks like two lines, with the same length, but pointing in two different directions. The difference in direction is what would show the different velocity. So imagine one line going down, one like going right, same length, but directions, so they would be different velocities.
The ratio of velocities of light rays with different wavelengths is always the same and equal to the speed of light in a vacuum, which is approximately 3.00 x 10^8 m/s. This means that the ratio of velocities for light rays with wavelengths of 4000 Å and 8000 Å is still equal to the speed of light, around 3.00 x 10^8 m/s.

No. "Velocity" includes a magnitude and a direction. If any of the two are different, then the velocities are also different.
Only if the two velocities are equal in magnitude but in opposite directions.
The angular velocities of a pair of coupled gears are inversely proportional to their radii. This means that the gear with a larger radius will rotate more slowly than the gear with a smaller radius. The ratio of their angular velocities is equal to the ratio of their radii.

Momentum is equal to the product of mass and velocity, so if the mass is equal, the one with greater velocity has greater momentum.

Yes.
Generally, no.
In a traveling wave, the relationship between the two velocities is that the wave velocity is equal to the product of the wavelength and the frequency of the wave.
