A yellow star. The Sun is definitely not a red giant; if it were to swell to the size of a red giant (like Antares, for example), our Earth would end up inside the Sun.
No. The Sun is a main-sequence star. It will not be a red giant for another 5 billion years.(see related link for an image of what the Sun would look like in its red giant phase

A Red GIant.
A giant star is smaller than the sun.
Color is related to surface temperature, and a "red giant" is cooler than a main sequence, medium-sized star like the Sun.

The sun is a star, much like the other stars in the universe. It is a ball of hot, glowing gases that emit light and heat through nuclear fusion reactions at its core. Just like other stars, the sun is born from giant molecular clouds, undergoes a lifecycle, and will eventually evolve into a red giant.
The Sun.
A red giant will be about 10 to a 100 times bigger than our Sun. However that is just a red giant. A red supergiant will be about 100 to 1,500 times bigger than the Sun, whereas a red hypergiant will be anything greater that 1,500 times that of the Sun - Like VY Canis Majoris.
