It varies from motherboard to motherboard. If I remember correctly, on mine there is only one other slot that shares lanes with the first slot. I don't think it's the last one. There's also a BIOS setting that forces a particular slot to use less lanes.
Your motherboard manual should have an overview of how the lanes are divided between slots.
