It takes the Sun (i.e., the Solar System) ca. 240 million years to go once around the Milky Way.
There are billions of suns in the Milky Way, it's a galaxy. Our milky way is forming about 2 suns per year.
The Milky Way is our galaxy, there are many, many millions of suns that make up the Milky Way

Our sun "The Sun" exists in a galaxy called "the milky way", all other galaxy's that we know of also have suns.
Our galaxy (the Milky Way) is estimated to have between 100 and 400 billion stars. A star is a sun.
There are lots of giants in our galaxy. Betelgeuse is very big (about 20 of our Suns). The massive object / system (expected to be a supermassive black hole) at the center of the Milky Way has the mass about 2.6 million of our Suns.
The sun is one of the many stars in the milky way - our galaxy. Sol, our Suns name is about 25 light years from the center of the Milky Way.
The sun is located in a spiral arm of the Milky Way galaxy, about 25,000 light-years from the center. In the universe, the sun is part of the Local Group, a collection of galaxies that includes the Milky Way and the Andromeda galaxy.
There are around 200 to 400 billion stars in our galaxy. It is more correct to call them stars, rather than "Suns", because the name "Sun" is the name of our star. You wouldn't call all Americans Sam, would you?
We expect the Andromeda galaxy to be just like our own Milky Way galaxy. We can see stars (suns) in the Andromeda Galaxy and just as stars have planets orbiting them in our galaxy, we believe that there must be planets also orbiting stars in the Andromeda galaxy.
The boundary of the Solar System is defined as the point where the Suns gravity no longer has an effect on any body. That distance is approximately 2 light years. The Milky Way Galaxy is about 100,000 light years across. So, the Milky Way Galaxy is about 50,000 times larger.
