Catalan, Spanish, English, Japanese - like, "speak-speak" natively, or quasi-.
I used to "live and work" in Mandarin, but that was a long time ago. Definitely rusty. And of course speaking two of them natively, I can live in any other Latin language.
And I can "survive" in Russian and Indonesian. It'd be mainly a matter of being exposed to them consistently and in real life, and I could probably upgrade those to "live and work" fairly quickly.
