Out of the following interactions, is this the correct order from strongest to weakest bond?

ion-dipole > hydrogen bonds > dipole-dipole > Van Der Waals

Also, is Van Der Waals the same as London Dispersing forces? If not, what is their difference? Thanks!

Yes to both questions!

Yes to both questions, ion-dipole interactions are the strongest because ions tend to have a strong charge which attracts the charged dipoles of other molecules.

Yes, that is the correct order of interaction strength, except that it is missing the ion-ion interaction which is the strongest interaction of all.

And yes, Van Der Waal Forces also are called London Forces. However, Dr. Lavelle prefers if you call the interaction induced dipole-induced dipole interactions.
