A guy suggested a site to me before. I think it was Specter well I am certain it was him. Anyways try get fluent in one programming language at first then take a more professional approach at a higher or lower level language. You do not want to jump into all these array of programming languages you mentioned. That would be very challenging and can potentially cause you to give up or stop trying or even lose interest. You just need to see it from a certain aspect. I will suggest 5 recommendations and I also will provide a few links for you to check out
1. Programming vocabulary
2. Experimenting & problem solving and error handling. Debugging.
3. Googling errors and reading why they are appearing and observe the information provided.
4. Ask a lot of questions.
5. For beginners I would like to recommend an IDE like VS (Visual Studio).
I am sure you can find ways of getting Learn C The Hard Way maybe borrow it from a pirate.
