Yeah those are all still biodiesel. Biodiesel isn't defined by feedstock, it's any transesterified lipid of biological origin suitable for combustion in compression-ignition engines. You can make biodiesel from all those things.
It sounds like the distinction you're making is between waste-manufactured biodiesel and new-manufactured biodiesel from rapeseed or corn oil or what have you. I suspect "renewable" is either marketing or a legal term, not a technical one.
