Here is an organization in Remscheid that offers various advice and services for refugees. I would contact them and see if there are any events coming up in the area where you could get to know some people, and what options there are for learning German as well:
Phone number: 02191 420399

There is also a Facebook group which you could message:
Best of luck!
