Pls Help! Need Help in lighting

I Need help… Lighting in my level looks really bad…

The look that I want…(it has 8 movable point lights and I am trying to make everything static but I am having problems)

And whenever I make a change the scene is too light/dark or there are black patched here and there if I like an attempt these are my attempts

First one is my favourite/the effect I need
Need to change the movable lights into static and need to get the same effect after building the lighting
