Answer
Insurance generally follows the vehicle, so it is very unlikely that the driver's (d-1) insurer will cover this.  The insurer for c-1 should cover the entire loss, unless they determine that d-1 did not have permission to drive the vehicle.

If they deny coverage because D-1 was not a permissive user, then your insurance company would handle your damages under Uninsured Motorist coverage.  This applies to both property and medical damages.

Since so many cars were involved, it is also possible that the liability policy for c-1 is not large enough to cover all the damages to everyone involved.  If this is the case, again your insurance company would handle your entire loss under Uninsured Motorist coverage.

If you have not yet done so, please report the claim immediately to your insurance company so they can investigate and help you.  They should be able to give you good advice on how to proceed.
