Main contenders I use often are: C# (work) C Scheme/GNU Guile (home) Bash (work/home) Powershell (work)
SQL can be included also - use databases a lot (MySQL, SQL Server, SQLite, Postgres)
You also have Javascript, which is required for web projects.
Odd areas have used Python for Raspberry Pi's or simple web api's. Not a fan of the language.
I have been playing with "newer" languages and, currently, really liking Odin. I am not sure I can be bothered to dive heavy in Zig, Go or Rust.
Java, C, C++, Prolog, HTML, CSS, JavaScript, PHP, MySQL, Haskell, Common Lisp, Clojure, Lua, PostgreSQL, MS SQL, SQLite, VBScript, Python, Ruby, ActionScript 2, ActionScript 3, Perl, MATLAB, Octave, Dart, Rust, assembly.
I'm probably missing some.
