Fake Languages You Can Actually Learn:
Klingon — a pretty famous fictional language from Star Trek. You can even learn this one on Duolingo. (Apparently, one Klingonist raised his child from a newborn with Klingon as their first language (along with English), though the child gave up Klingon at the age of five.)

Unlike with some other retroactively created languages, supposedly Tolkien started by inventing languages before writing, with the most famous and elaborate ending up being the Elvish languages. http://councilofelrond.com/content/guide-to-learning-elvish/. Among these (Westron, Sindarin, Quenya, Khuzdul, Entish, Black Speech, Adûnaic, Rohirric/Rohanese), you can learn to speak the Elvish languages Sindarin and Quenya, as well as possibly Westron and Adûnaic, to an extent… There is a book, "The Languages of Tolkien's Middle-earth" by Ruth S. Noel, that might help…
Na’vi – Created by linguist Paul R. Frommer for the making of the Avatar movie. You can learn Na’vi here on https://learnnavi.org//their YouTube channel or here: https://kelutral.org/
Dothraki – from A Song of Ice and Fire/Game of Thrones. You can learn Dothraki on https://dothraki.org/. This language also has a subreddit (r/learnDothraki) and a Living Language book.
High Valyrian – You can learn High Valyrian from ASOIAF/Game of Thrones. It has a course on Duolingo.
Second Tier:
Mando’a – http://mandoa.org/. From my understanding, this is the most fleshed-out Star Wars language (the language of Mandalore and the Mandalorians.) The Oyu'baat community and Project Shereshoy both have reference materials on the Mando’a language (and culture.) Mando'a Lessons - YouTube
Ewokese — A Star Wars language from the planet Endor. You can’t really become fluent, but there are quite a lot of words you can learn. The same is true for the Jawa and Huttese languages. The Complete Wermo's Guide to EWOKESE

Chenuh – The language of the Chiss from Star Wars. While it was not canonically fleshed-out, fan-made projects made learning Chenuh possible. On the other hand, the Chiss have superior vocal capabilities, so you’ll never be perfect.

Ur-Kittât (Sith) – Star Wars language of the Sith species. Imperial_Cadet on Reddit and YouTube is working on analysing and developing the language.

Yautja – The Predator language. Alphabet

Dictionary: here or here (English alphabet)
This does not account, however, for the other aspects of the language like their ‘silent hand’.

Bonus: A Few Alphabets:
Aurebesh/Galactic Basic Standard – a Star Wars alphabet (‘Aurebesh’) seen here. You can learn more information on https://aurebesh.org/. Once you learn that, you can even have Aurebesh key caps (here, here, here). (<-- I don’t like the fact that some of the non-letter keys are just Star Wars symbols; it doesn't seem to me like people in the galaxy would just have a key for the rebel alliance, etc.)
Gnommish — the language of the People, or faeries, from Artemis Fowl. This language is traditionally written in spiral order outwards. There’s a guide to the original alphabet in the Artemis Fowl Files. (This one is less complete than the others, as it is only an alphabet and occasionally contradicts its canon; it is mostly here for sentimental value.) Gnommish alphabet (Note: The new Gnommish looks like this, and was the version created for the movie.)
Standard Galactic Alphabet — The “Minecraft Table language” is, in addition to being used on Minecraft enchanting tables, actually from the Commander Keen games. Unfortunately, it won’t get you very far, because, while it IS a real translatable alphabet, these translations often lead to nonsense ramblings and useless information in the Minecraft games. Here's what it looks like.
Hylian – The Legend of Zelda. Hylian’s more complicated than it appears, even if it is just an alphabet. There are several different Hylian scripts from across the games: look here, as versions of either Japanese or English cyphers, in addition to the Gerudo and Sheikah scripts.
