All ground splices must be done with the same rules as any other splices: inside a junction box or using some sort of splice listed for use outside of a box. For details, see the National Electric Code, NFPA 70 (2014) Article 250 — Grounding and Bonding . 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 .

A single wire running through the box counts as one wire. The amount of ground wires does not matter. They are counted as one conductor regardless of their amount.
It seems mildly annoying if I slice the grounds for each branch circuit and then run them to the grounding bar in the panel; doable, but more wires to consider for conduit fill math. Can I, instead, put a grounding bar in the junction box and run a single sufficiently large grounding cable to the breaker grounding bar? box fill for 12 awg wire has a multiplier of 2.25. the ground wire is only counted once so with 3 cables plus the feed 1x2.25 for the ground 8x 2.25 for the 4 hot and 4 neutral. There is no switch or device in this box so we could skip that but if there was 4.5 adder would be needed because 2x of the largest wire connecting to it.
