Chinese (Mandarin): Native
English: fluent enough for hobbies and casual conversation
Japanese: basic. Learned from college class for 2 years, watched anime forever. Mada mada desu yo!
Taiwanese Hokkien: know a little. Grandma only knows this one, not so much of Mandarin. It’s a bit hard to talk to her or understanding what she says. Don’t worry, we still love each other. 
C, Java, PHP, SQL: a little
Python: alright 
Serbian: native
English: advanced.
Dutch (native), English (fluent), French (fluent)
Got quite extensive German vocabulary but my grammar ist Scheisse.
Passive Spanish.
It’s never too late to start 
Particularly if you have people to practice with.
Nah, would be extremely hard. The only reason I was able to learn English was because I was glued to the TV, Cartoon Network to be exact, ever since my parents bought a colored TV when I was around 4. At that age I also learned English words / songs in pre-kindergarten. I was able to memorize the words and the meanings by some of the gesture or events in cartoons. Old Hanna-Barbera cartoons are a good example.
By the third grade in school, when they started teaching English, I was already a “pro” at speaking. 
Romanian, native.
Italian, native.
And English with a good accent natives told me. I try my best 
I speak:
Learning languages is fun, I think. And I want to keep going after Italian as well. I have a rather intense list of languages I want to be able to speak, including Spanish, German & some languages of the East.
What is a bit fun with me though, and that I am quite proud of, is that I am legally deaf - yet I have always had quite the ear for languages, I mean… That sounds like an impossible combination.
Replace TV with YouTube and that’s my lil brother. Never understood how he has learned English from YouTube by watching Minecraft and Among Us videos.
Never understood how people learn languages by watching or reading something.
Maybe I’m oldschool and trust in standard learning. School, college, courses…
I think that’s because of motivation purposes. It works for me. Hobbies are the reason I got to learn English. Grand Theft Auto series didn’t have official Chinese version until GTAV, so I used to learn the language by constantly going bowling with my cousin. 
I watch anime with original voice over, too. Realistically, Japanese don’t speak like anime characters. But you get to learn a few phrases from it.
English, and Spanish profanity. Have wanted to learn each foreign language Resident Evil has used since 4 so I can understand what talking enemies are shouting at me.
I recently found something relating to this. If you are interested you might want to look out for the hole in the wall experiments.
Here’s a TED talk:
I’m not sure how accurate this is to actual learning but from what I understand from the talk most children do not need formal education to learn something properly as long as they have access to resources like books, movies, the internet, etc.
I also found another video from someone who learned English from Runescape:
English: native
Russian: don’t know what level I’m at technically but I’ve been studying it everyday for 2 years. it’s a beautiful, complicated language
I bet any non-native language is complicated 
Good for you nevertheless
English
French (learned for 8 years, yet I don’t know how to say “floor”)
Well since no ones said it…
The Language of Love. Fluently. With my weiner.
And English. Also with my weiner. 
native language: English
German: know a little bit and chose it cause my great grandfather was German.
I’ll guess Arabic. I think there’s more than 200 million native speakers for only a handful of languages and you ruled out English and French.
French arabic and some english
