Should I learn oop first before any other programming language? If yes could you tell me an online courses?

Answer 1

No, not at all.
Id recommend you analyze your motivation that brings you in this sphere. If you want to get really quickly money you can learn webdev and language such as python or js and both support oop.
If you are pretty young and you have a lot of time you can begin with C language that is pretty simple and small language but it makes you better programmer.
