They come in all different shapes, sizes, colors, unusual features, etc.
If you counted 1 number per second, it would take 7.5 months to count all 20 million sentient species in the Star Wars galaxy.

It isn't currently known whether ANY alien creatures even exist - sentient or otherwise. Should you find any specific information that tells you there are so-and-so many species, that would be all made up, since there is currently really no way to know.
You can make 100 billion separate books that has the descriptions of about 10,000 trillion sentient species (100,000 per book) by simply orderly compiling them.
The average number of stars in a dwarf galaxy since it contains a few million to several billion stars with as few as ten million (107) stars.
About 2.5 million light years from Earth, but since the Earth and Sun are only 8 light minutes apart, there isn't that much of a difference in how far the Andromeda Galaxy is from the Sun or Earth. So the Andromeda Galaxy is about 2.5 million light years from the Sun and Earth.
Since BX442 is a spiral galaxy 10,700 million light years from us, it will take 10,700 million years per second for the message to reach its intended designation (and an additional 10,700 million years per second for any reply from an alien civilization in the BX442 galaxy).
The 'Star Wars' galaxy is part of science-fiction. It does not exist in the real world, so you will not be able to actually place a location of it. But, if you are refering to the where the Star Wars galaxy 'exists' in relation to the movies, then the the only information I know there is that it is 'far far away', and that's it's suggested time-frame would be a 'long time ago'. Since E.T.'s home galaxy is 3 million light-years from Earth, and his species appeared in SW1:TPM, his home galaxy might actually be the Triangulum galaxy (which is 2.7 million light-years from Earth).
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.
Probably not since the closest galaxy to us is M-31 which is over 2 million light years away.
Since PGC 169337 is a spiral galaxy 1200 million light years from us, it will take 1200 million years for the message to reach its intended designation (and an additional 1200 million years for any reply from an alien civilization).
Since PGC 2416052 is a spiral galaxy 2000 million light years from us, it will take 2000 million years for the message to reach its intended designation (and an additional 2000 million years for any reply from an alien civilization).
