What language is the best?
todays is better to ask - what freamework is the best for...
For all of them you can become a freelancer/self employed but I think software development offers a good salary
yes of course, but which one have better salary?
There isn't any "best" language. Some languages are better at some task while other ones aren't. But you can still use one language to do every code, but some of them would be faster and more efficient with a different language. For a job at a company: Java For web sites: HTML, CSS and JS and PHP For Windows apps: C++, C#, Java For Android apps: Java, C++ For apple's platforms: swift This should help a bit.
