LDF is a type of Van Der Waals.

Van der Waals is usually used to describe all intermolecular forces. LDF is always included in it.

Yes, the answers above are correct. And since LDFs are usually the weakest and temporarily attractive intermolecular forces, most molecules will experience LDFs.

Van der Waal Forces include dipole-dipole forces and LDF. In the lecture notes, however, Van der Waal is written as another name for LDF. I would recommend just use the name LDF when you are referring to the induced dipole moments between molecules.

I just wanted to add on that the book uses the term LDF and not Van der Waals, so I personally would stick with that.
