The list of the imaginary Star Wars reference books are: The Essential Guide to Planets and Moons (contains 50 million inhabited systems (incl. planets and moons) and 69 million colonized systems (incl. planets and moons)) The Essential Guide to Sentient Species (contains 20 million sentient species in the Star Wars galaxy) etc.
No. There won't be a Star Wars reference book that has all the info and descriptions of 20 million sentient species (because, in addition to the large sentient species portraits, each 1 1/2 page will give a detailed description of the sentient species of every shape, size, color, unusual feature, their histories, and what planet and moon they're from, and it will be 30 million pages in length).
No. There won't be a time they will make a Star Wars reference book (similar to The Essential Guide to Alien Species reference book published in 2001) that will contain all the info and descriptions of the 20 million sentient species (excluding non-sentient and extra-galactic ones) in the galaxy of every shape, size, color, and unusual feature because it will be at least 30 million pages in length (In addition to the large alien portraits, they get a 1 1/2 page detailed description of the species, their histories, what planet or moon they're from, and what books or movies they're in). Due to the 30 million pages in length, it will be in 12,000 separate reference books (2,500 pages in length per book).
Yes. It might be possible that there are countless sentient species in the universe, but we do not know for now.
Yes. All sentient species do have unusual features. But for now, it is unknown.
The Star Wars galaxy is FICTIONAL, as would be any such reference book.
Yes. Sentient species come in all shapes, sizes and colors.
No. The authors, including Daniel Wallace, can't make a Star Wars reference book that has all the info and descriptions of 20 million sentient species in the galaxy, because it will be at least 30 million pages in length (1 1/2 pages for each of their large portraits, their species, their histories and what planet and/or moon they're from).
We only know of one sentient species, homo sapiens. One example is an insufficient basis upon which to generalize about how many arm sentient species might have. So the question cannot be answered at present
