A few days ago my power wire coming from my battery melted off at the relay connection. I think it was because of a bad ground. Anyways, I fixed that but now i'm noticing the relay is warm to the touch after driving around. Is this normal? It's not so hot that i can't touch it but it's definitely warm.

 

A little warm is normal, as in just a bit above ambient temp, a decent amount of current is going through it. They should not be hot though. If you're concerned, double/triple check the ground for the relay and the ground for the fuel pump.
