Why I have added a lot of lights, but only a few of them are displayed on the debugging page, but not all of them are displayed

By default the maximum number of lights per material is 4.
You may change it with material.maxSimultaneousLights = your_number

Also there a way to control which meshes will be lit. A mesh can be added to the excludedMeshes array or add the ones not to be excluded to the includedOnlyMeshes array.
