C# => Free; Java => Free; Common Lisp => SBCL is Free; Python => Free; Ruby => Free; C => Free; C++ => Free; Rust => Free; Haskell => Free; JavaScript => Free; Smalltalk => Pharo is Free; Perl => Free; Forth => GForth is Free; Fortran => GFortran is Free; Kotlin => Free; Scala => Free; Clojure => Free;
Now there are some paid languages like Wolfram Mathematica, Allegro Common Lisp, Lispworks Common Lisp, Delphi Pascal, Dyalog APL, IBM Fortran and some languages with paid tools like Visual Studio for .NET and the Ultimate Jetbrains IDEA IDE for Java/Kotlin/Scala. Clojure has the paid "Cursive" IDE to go with the Jetbrains IDE. However, you can use other Free IDEs to go with most paid tools (Ex: you can use several alternative IDEs for C# and Emacs for Clojure). Also, the "paid" languages are fairly niche in comparison to the free ones at the top. How many people do you know writing Dyalog APL, IBM Fortran, Delphi, and Lisp works programs? How many people do you know writing C#, JavaScript, Java, C, and Python?
If we're just talking about software in general, then yes there is a TON of expensive and closed source programs and I don't expect that to change anytime soon.
