Where to start really learning code?
I want to try and learn as many coding languages as I can, but I don't know where to start. All the resources I have come across are made for children, or only go over the absolute basics.
Are there books or sites that can really make me learn one entirely?

This is a bad mindset. Any sort of beginning programming school is going to go over just the basics. If it's "made for children" then you should be able to breeze through it, but you'd still learn. Once you know the basics, just do whatever you want until you feel comfortable with your knowledge, and ask people who know their shit to help you.
Depends on what you want to learn. Codecademy is a great way to get your feet wet in a bunch of languages, but they currently don't offer the C family.
If you're looking for a one-stop resource to use from start to mastery then you need to rethink your approach to programming and learning in general.
The closest thing for you, however, is a beginner - intermediary book such as The C Programming Language.
