True
Galaxies do exert significant gravitational attraction on other galaxies. For example, the Greater and the Lesser Magellanic Clouds are galaxies that orbit our own galaxy, the Milky Way. In that sense, the stars in one galaxy do have a gravitational interaction with those in other galaxies. Of course, the more distant galaxies have correspondingly less gravitational interaction with ours.
true
Yes, there are. These generally come about when they are ejected from their host galaxy by the huge gravitational interaction involved in the collisions of galaxies.
The most important star in terms of gravitational influence on our solar system is the Sun. Its gravitational pull keeps the planets in orbit around it. Additionally, the interactions between stars in a galaxy are primarily driven by their gravitational forces.
Another word for galaxy is "star system" or "stellar system."

A satellite galaxy is one that revolves around another galaxy.
No. It's the mutual gravitational force between it and the earth that keeps a satellitein a closed orbit, instead of flying off away from earth in a straight line.Technically, there's no such thing as "outside of" the gravitational force of anything.We can calculate the gravitational force between a star in a distant galaxy and the earth.In fact, we can calculate the gravitational force between a star in a distant galaxy and you.The force is pretty small, but it's there.
true
The farther away another galaxy is from our solar system the less effect that the gravitational pull will have on that galaxy.Thus allowing the other galaxy to travel at a faster rate.
There is no limit, and it never ends. The formula to calculate the gravitational force at any distance has no limit in it. The force of the gravitational attraction between the earth and another object can be calculated even if the other object is in another galaxy. Of course, the farther apart two masses are, the smaller the gravitational force between them is. So when you're far from the earth, there's probably something else nearby that attracts you with a stronger gravitational force than the earth does. But no matter how far away you are, and how weak it gets, the earth's gravitational force never ends.
By gravitational pull from the galaxy
Massive means there is a lot of mass - and gravitational attraction depends on the amount of mass. The amount of gravitational attraction also depends on the distance - i.e., the effect will be less at larger distances. The gravitational attraction between galaxies is strong enough to make galaxies in a galaxy cluster stay together - for example, in our Local Group.
The force of gravitational attraction between two masses is never zero. There is a force of gravitational attraction between a hair on your head and the smallest moon in the farthest galaxy. The force may be too small to measure, but it's never zero.
A point where the center does not have gravitational pull... once things stop orbiting thats it for the galaxy
They would still pull on the Earth, the Sun, and our galaxy. But their individual gravities would be nearly indistinguishable as part of the overall gravity of the parent galaxy. The variations in our gravity due to other stars is negligible compared to that of the Earth, the Sun, and objects within the solar system. But the combined force of many stars are what keep the galaxy from flying apart, and what draws galaxies toward each other. The Earth, being our closest large mass, exerts many times the pull on earthly objects as the distant Sun. (Gravity is inversely proportional to distance from the center of mass.)
