I don't use APL, but I do occasionally use j (
https://www.jsoftware.com/), which is basically APL without the special character set, although mostly for fun. I have not written any FORTRAN in a very long time, but I still compile FORTRAN code every once a while. As other noted, LISP is going strong, it's the only one on the list that I use somewhat regularly.
Speaking of old languages, in mid 80's I was on a team that worked on a machine translation system, and we used a language called Q. The few keywords the language had were in French, and it was based on tree rewriting. I wonder if that is still around.
