Using 3 6vleds in Raspberry Pi

Hello? I'm asking you a question because I don't have enough knowledge in electronics!

I'm going to run dozens of 6v leads on Raspberry Pi. I think the number of leads that are turned on at the same time is three, so I just need enough power to turn on three at the same time I want to know if Raspberry Pi can cover with its own power

I thought Raspberry Pie would cover up to 6v since it's 5v If all three lights are turned on and the voltage is as necessary as all of them are added, I'm asking because I don't think the lights will turn on at all. The Raspberry Pi port does not directly give 5v, but the signal is sent through the port expansionic.

There are 2 or 3 5v pins from Raspberry Pi, so would it be okay if you connect them separately for each ic? Is it useless to be on the same pie?

Please answer!
