Without a lot of calculating, on that short of a run, 14 ga will easily handle 15 amps and 12 ga 20 amps.

Lights are about 35 watts so that's ~ 6 amps each; wiring the front two in series would be with 14 awg, generator output should be around 20 amps so it's 12 there, ignition runs like 5 amps so 14 is more than plenty for that.

Starting current is about 200 amps so your battery-starter loop should be at least size 00. Even if it's lower than that 00 won't hurt you and on cold days you'll be better off with it rather than lighter wire.
