3 way switches for 6 lights.

I am trying to reconfigure my overhead lights in ahallway. The power is supplied to the first light, and then runs with a 3 wire cable to a second light which has two three way swithces wired there. There is a light branching off that second light run by the switches. I want to add lights between the first and second light, and after that second light. Do I need to connect all the lights with 3 way cable, or is there another solution?
