I cannot find a diagram for my setup
power-(12-2)-light-(12-2)-switch-(12-3)-switch-(12-2)-light
both switches are 3-ways

everything works, but the first light is dim. And when i take the bulb out of the first light, the second light dims.

Assuming this is the ONLY place in the house this is happening:
check the voltage and all connections.
odds are something is loose
(and probably where everything ties together in that first light fixture JB)

Can not work the way you describe- you have no way to get the neutral to the last light.

that is what i read. Someone explained that i would need another 12-2 wire connecting both lights:
"=" means 14/3 and "-" means 14/2.
Power-L1-S1=S2, and L1-L2

but i did not understand how to do this

12/2 to switch 12/3 to switch 12/2 to light 12/2 to light.
Box 1 switch box
Connect whites together
Connect black from 2 wire to common screw
Connect red and black from 3 wire to traveller screws.
Box 2 switch box
Connect red and black from 3 wire to traveller screws.
Connect black from 2 wire to common screw
Connect whites together.
Box 3 light one
Connect blacks and pigtail out to light. Connect whites and pigtail out to light.
Box 4 light two connect black and white to light.

If you add a wire between the lights to carry the fixture you'll be only useing the white from the cable. Legalities aside as an electrician I would frown on running your neutral a seperate run from its power. We aren't allowed to run a neutral in a different conduit from its hot. Not sure offhand how it works for romex runs. Someone more well versed in the nec can answer that I'm sure.

so should i just bypass the first light with the incoming power so my sequence becomes
power-switch-switch-light-light
so the 2nd light is only connected to the 1st light
