I have two switches, (one inside the house, the other at the front of the garage). These control 2 lights in the ceiling of the garage. I would like to install 4 new LED lights, and change the existing 2 lights into junction boxes. 3 wire runs in both switches. On one light base, there is 2 black, and 2 white. On the other base, there is just a black and white. Can I add a new 2 wire into this base and run to the new LED light? Marette off the black and the white wires? I hope this makes sense.

If you use the hallway circuit to power the three-way circuit, you must run four conductors (plus ground) between the two switch boxes.
(If you needed to use the dining room feed you would have to run five conductors.)
With this circuit, you abandon and cap off, or remove completely, the feed cable to the dining room switch. You also abandon and cap off, or remove completely, the useless stub cable to the terminated j-box. I have omitted those cables from my diagram.
I have omitted the fault ground wires from the diagram, but don't omit them from your house.
Using the hallway light j-box as your power source is safer than using the dining room switch j-box. With power coming from the old dining room end, the two-gang (the one with the hallway switch) would have live wires from two separate circuits. A future electrician might not know that he has to flip two circuit breakers to make the box safe to handle.
I think you have mis-identified the "hot" wire. Do you have a multimeter? Assuming your box is actually grounded, carefully measure the voltage between the red, black and white wires to the box. If only one has 120 volts on it, then that is your hot wire. If 2 wires have 120 volts, then someone did a bad thing and wired the switches to break the neutral.
Another way to identify which wire is hot is to pull down the light fixtures and examine the wiring. Don't disconnect anything without taking notes about how it was hooked up first!

Yes you can, you can add those 4 LED light fixtures. Just connect parallel from your existing neutral switch wire and neutrals of the 2 light fixtures that you will be changing.
