A galaxy is many many times larger than one sun.
Betelgeuse is approximately 900 times larger in diameter than the sun, about 1.5 billion kilometers.
Capella is about 90 times larger in surface area than the sun.
Jupiter is the largest planet in the Solar system, but it is not larger than the Sun. The Sun is about 10 times larger than Jupiter.
The sun is 109 times bigger than the earth. You could lay 109 earths across the sun and it would circle the sun.
Antares is about 800 times larger than our Sun. The Sun is about 109 times larger than The Earth. So Antares is about 87,200 times larger than The Earth. So you could fit about 663,054,848,000,000 Earths inside Antares. (663 trillion) See related link for a comparison to the Sun

The Sun is somewhat midrange in size. All Giant and Supergiant class stars are larger, some of which many times larger, than the Sun.
Stars are significantly larger than Earth. For example, the Sun's diameter is about 109 times that of Earth. Larger stars, such as Betelgeuse, can be hundreds or even thousands of times larger than the Sun.
