Large sized Simon

I am attempting to build a large Simon game that I can wear as a Halloween costume. I was using the following project as the base of my project...

Heres my question. I want to replace the led's in the schematic with a 5v contact so I can have 5 LEDs per color instead of just 1. Relay SPDT Sealed - COM-00100 - SparkFun Electronics

How does this effect my resistors?

This is my first project (besides the ones that came with my starter kit), so thanks in advance for all the help!

I want to replace the led's in the schematic with a 5v contact so I can have 5 LEDs per color instead of just 1.

Can you explain what that means, please?

In the schematic there are 4 different colored LEDs. 1 color for each push button. For my purpose I need each color to consist of 5 LEDs instead of 1. I am not going to power the LEDs off the Arduino so I plan on using a relay. So when the led would light up, instead the coil of the relay would be energized and then the LEDs that I have attached through the relay would light up.
