I'm pretty well covered here; I'm extremely comfortable with and have extended professional experience writing Java, Python, PHP, C#, SQL (plus PL/SQL), and JavaScript. Aside from the C/C++ duality, my experience rounds out the top languages on all of the lists.

I also have more limited experience with some of the "fringe" languages, like Ruby, Shell (I'm assuming they mean Bash?), Scala, and Perl. And of course, I've been using HTML since I was 14, way back in 1995-- although that's not a programming language (yet I mention it, because it's on some of these lists). And I have 5+ years of professional experience with Visual Basic (in the form of VB.Net) too.

My limitations are more around the frameworks for some of these languages; I've heard it said that you need ten years of full-time experience in a language to be an "expert" in an entire language's ecosystem. And the only language I'd say I'm a full-stack "expert" in is C#-- although Python is slowly starting to become a runner up for me.
