Do you know how powerful your lights are?

Because unless they’re super-bright, arc lamps you could just combine all the power and all the ground cables together and solder them onto the (cut off end) of a Raspberry Pi power supply.

An 11W LED light is super, super bright. And at 5V would pull 11/5 = 2.2A

If your LEDs are 4W or less, you could power them all from a single “official” Raspberry Pi power adapter (or any 5V supply that can provide 3A). Simply divide the power rating of the LED light by 5V to get the current rating.

You could always wire three lights into one and use two power adapters (which would allow you to run two banks of 8W lights). Of course you could just get a single, powerful 5V supply (like you get for LED drivers) that can provide, say, 10A but I was trying to keep it simple, using parts you can easily and readily get hold of 😉
