Need Help with a Scene. Graphics artifact and vertex issues

Hello,

I’m using Unity 5.6.1. The problem I have is setting up a scene lighting. I’m not sure if it deals with the vertex of the meshes. They are low poly as I can get with a UV unwarp. I can provide pictures of settings.

The problems I have are. Shadows does not show correctly sometimes, due to vertex lighting some objects lighting matches the trangiluted mesh not the lighting in the scene, and I am not sure emission materials are actually baking the light.

Any suggestion or help is appreciated.
