Since Betelgeuse is a nearby star (compared to the size of the galaxy, that is), you can assume that it takes about the same time as our Solar System to orbit the galaxy - approximately 240 million years.
Rigel and Betelgeuse are not orbiting each other. They are independent stars within the Orion constellation and are located at significant distances from each other. Their apparent proximity in the sky is due to our viewpoint from Earth, but they are not gravitationally bound and do not orbit each other.
Rigel is beta Orion so I am not sure what the question is about.
No one really knows, because no one has ever been to Betelgeuse. It would take much more time than getting to Pluto.
Betelgeuse does not actually rotate like a solid body, as it is a supergiant star with an irregular shape due to its strong pulsations. It is estimated that Betelgeuse has a rotation period anywhere from tens to hundreds of years.
The Milky Way and the Andromeda Galaxy are the two giants in our local group. These two galaxies will collide, but neither one can be said to orbit the other. In some instances smaller galaxies might "orbit" a giant cluster, with periods measured in billions of years. Galaxies in general do not orbit anything. Instead they are all simply spreading further and further apart as the universe expands.
It takes approximately a quarter billion years.

About 230 million years
About 2 minutes through a wormhole - you turn left at Betelgeuse and then take a right at Sirius.
The Sun - and the Solar System - are about 26,000 light-years from the Milky Way's center. It takes an estimated 225 million years to go once around the galaxy.
It takes approximately 230 million years for the solar system to orbit our galaxy at a speed of about 828,000kph (515,000 mph)

It takes the sun to complete one orbit (a galactic year) of our home galaxy: 226 million years
millions of years, but it varies with location is the galaxy. for example in the milky way our solar system orbits once every 225 million years but stars further out orbit slower and those further in orbit faster.

Do you mean how long does it take Mercury to orbit the sun ? 87.969 days
