PLEASE help me identify these Newts

I need to know how to properly care for them, what they eat, etc.

Please if anyone knows what kind they are, let me know!

Those are Desmognathus but i can´t tell the species.
They are considered salamanders not newts.
Before you decide to keep them, please check if the laws of your state allow you to do so. Also, realize that bringing an animal home about which you know nothing, is a pretty bad start.
If i were you i´d put those back, and start properly, find a species that appeals to you, learn as much as you can, set-up the aquarium/terrarium, and then get the animal. CB is your best choice as it ensures you are getting healthy animals which will be completely used to captivity.
If you are determined to keeping them though(after checking legality), you can find information on Desmognathus husbandry by using the "search" option on this forum. There´s currently no caresheet for desmognathus but you will be able to find experiences from other users around the forum.

How do I figure out if their illegal? I'm in SC

All native Desmognathus species ARE LEGAL in South Carolina. It's probably Desmognathus fuscus in which this care sheet should help you out. South Carolina is one of those states where their legality information is scattered all over the place, so there isn't really one place to go look for it. You can also forget about SCDNR website cause it's useless.
