Without going into all the details about no free breakers, location of

or "no it's not code" answer to this question:

There's a junction box with a 14/2 without ground coming directly from the
panel. Leaving this box is a 14/2 without ground and a 14/2 with ground.
The ground wire is attached to the junction box but of course it isn't
actually grounded.

Can you run a single insulated ground wire from the panel to the junction
box to provide a ground for the 14/2 with ground that leaves the box.

The 14/2 without ground that leaves the junction box goes to GFCI
receptacle as the first receptacle on that run. That's fine for now.
However, the 14/2 with ground goes to some receptacles which should have an
equipment ground. My friend would like to add that ground in the easiest
manner possible, which is to simply add a ground wire from the panel the
junction box. Can he do that?

Thanks!
Yes, you can, but as others have said, it makes a neater job to install
a new cable to the box. This way it is also clear what the cable is and
what it's doing. A single ground conductor, bare or green isn't
necessarily going to be obvious as to it's purpose and could be cut or
removed unintentionally
