It really depends on what you want to do. If you want to be an "all-purpose" coder like you mentioned, then just start with basic beginner-friendly languages like HTML, Python, functional languages, and things of the sort. Some intermediate languages include PHP, Perl, Bash, Ruby, etc. Hard languages would include (nearly) all variants of C, all variants of Assembly, basically anything that has to do with low-level/machine-level programming. Once you become experienced, you'll be able to learn any language in just a few days. It's just a matter of how quickly you're able to memorize the syntax for said language.
