The third wire is connected between one of the traveler terminals of the two 3 way switches. Use a yellow wire nut and twist all four wires together.
Common wire is wrapped three times around the two traveler wires for the 3 way switch on the right. Connect the 2 ground wires with a fourth wire nut. The first wire is connected to the main energy source and its destination is the common terminal or the black screw of one of the 3 way switches.
Connect one wire to the first switch in the box and the second wire to the other switch and connect the black wire from each of the lights to the other terminal on its respective switch.

You have the power supply white wire that leads back to the breaker panel and you have the three white wires that connect to the three fixtures.
Currently you have a total of four white wires. Take the white wire leading to the second box and mark its end black too. Attach this to the lower brass screw on the right side of the first switch.
I have put together a course that walk you from a to z with residential wiring the course was put together with the amateur in mind so it is pretty easy to f. The white or neutral wires bypass the switch so the one coming from the power source and the one from the light get spliced and capped in the box. Connect the black wire coming from the lightbox with the black wire leading to the second switch by twisting their ends together and fastening with a third wire nut.
Connect it to the. A common application is in lighting where it allows the control of lamps from multiple locations for example in a hallway stairwell or large room. Connect the white or neutral wires together in the gang box.
