other than english of course: Psy is preeeetty much fluent in Chinese (great-grandparents are immigrants, grandparents' first language, and mama is fluent ((but rusty)) and they took 2 years of it in high school) but they don't use it all that much. and they took Spanish in middle school so.. they have a middle school curriculum of Spanish under their belt as well lol (so not very much. they mostly just watched movies in spanish in that class and didn't learn very much)

Melody took 3 years of French in high school but is kinda rusty and out of practice with it. She could have a conversation in French if she really needed to, but it would be rough.

Jett is currently learning Japanese. He started (slowly) teaching himself through online stuff when it was in high school, and is now taking Japanese classes in college!

Tate took Spanish in high school and hella slacked off in that class. He learned absolutely nothing. "yeah i know spanish i took two years of it" *someone says something to him in spanish* "uhm. haha *sweats*"

Guy is fluent in Tagalog and Spanish and is conversational in like, a BUNCH of languages including ASL! He really enjoys learning new languages and learning about the culture of the languages as well :)
