Can I monetize my app which uses external libraries? [on hold]

I am planning to publish my app on the play store. I've used a few libraries which are under various licenses. My question is, can I make the app paid or monetize the app, without giving out the source code? Or do I have to give away the source? And do I also have to pay any kind of royalty to these libraries if I'm earning from the app?

Thanks in advance.
