What are all the languages used in the film 'Embrace of the Serpent'?
The NYTimes review says there are nine but doesn't mention all of them.
I recognized German, Spanish and Latin. I would add Portuguese but Imdb says it's Catalan. Does Karamakate speak the same native language throughout the film or does he use more than one?
The other languages are all different indigenous languages. There are many throughout the film, some that the main characters understand, and others that they do not know. Ocaina is spoken the most, and there is also some Ticuna, Bora, Andoque, Yucuna (Jukuna), and Muinane, according to the actor who plays the older Karamakate in an interview with him (in Spanish) that you can find on youtube. You can find relatively up-to-date information on each of these languages at Ethnologue https://www.ethnologue.com/country/CO/languages
