It means that the newer mod will overwrite some files in the older ones. It also says which files are changed. If you post those we can tell you whether it's important or not.
The lighter grey means that those mods have been altered, and you can't remove them without first removing the mod that changed them. If you try to remove the lighter-grey mod it will tell you this and tell you which mods must be removed first.
This is also explained in JSGME's user Guide.
