Conservation of energy and of momentum are different things. Momentum is always conserved in a collision.
If the collision is perfectly elastic, kinetic energy is also conserved. Billiard balls are very nearly perfect. (I guess nothing is exactly perfect in this world.)

Unlike momentum kinetic energy is not conserved as a rule. Energy comes in several forms; chemical potential, gravitational potential, kinetic, sound, light, heat, etc. During a collision KE is converted to several forms of energy (though some are neglected in ideal models).

Well physics is not my forte but from my own experience with billards the kenetic energy from a collision appears to be transfered from one ball to the next with some of that energy still in the original ball in motion. I would assume that is a form of conservation of kenetic energy.

It depends on the angle of the balls collision of how much will the other gain in speed and how the other will lose. Great question

do you mean between 2 billiard balls? because yes! that's the basic definition of a ELASTIC COLLISION! don't you have a physics textbook?

If the balls are the same mass, yes.
