I guess you just used too many (different?) styled lights. I think you can use up to 4 of them in a close area.
The grey tiled looking textures mean that is something wrong with the shader. Either there is a missing texture or you wrote a wrong shader.
EDIT: The cause why you have so many lightmaps (tga-files) is that all the styled lights generate different brightnesses, and this needs some more lightmaps (one for each "frame"!).

It's just a warning, however, and the unused styled lights will just not affect the surfaces.
To correct it, eliminate the additional styled lights, or use the same styles on multiple lights.
