No, not only the earth and all of the other known planets have a gravitational attraction, but any object of any mass carries with it a measurable gravitational attraction to any other object of mass. Which is why it is said that the moon doesnt just revolve around the earth, for instance, but that the earth and moon REVOLVE AROUND EACH OTHER.

yes and no, planet earth is the only earth with gravity because there is only one earth, however planet earth is not the only planet with gravity or even the only object with gravity. every single planet and every star and even every comet or asteroid has gravity but its not just objects in space; everything is made of matter and all matter attracts other matter which is what causes gravity so the chair your sitting on, the computer in front of you, and even you have a small amount of gravity.
