The have all 5 phases like the moon. New, Crescent, Half, Gibbous and Full
Yes. Mercury and Venus have phases. We can't really observe phases for the outer planets, because we always see the bright side, since we are on the same side as the Sun. Any asteroid that gets near enough could also have phases.
If you could somehow stand on Jupiter's surface and observe Ganymede (and any of the other moons,) then yes, they would exhibit the same phases as earth's moon.
