I was wondering I have a HIS radeon hd 6670 in my pc right now and want to get another graphics card to add through sli cable. There are tons of different types of Radeon hd 6670 and was wondering if I could use those Ex. Gigabyte radeon hd 6670 , Asus radeon hd 6670

The brand doesn't matter.
All that matters is that it's the same card chipset (in your case, the HD 6670) and they have the same amount of memory, the same memory type (DDR3 or GDDR5) and that they have the same clock speeds.
Therefore, you could run an ASUS HD 6670 with a Sapphire HD 6670, as long as memory amount/type is the same, and clock speeds are the same.

By the way, sli is for NVidia cards. It's called Crossfire for AMD cards ;)
 


They should work with one another, its always safer to get an identical card but as long as the firmware and chipset are the same it will work.

Just take note that if the clock rates are different it will downclock speeds on one card to match the other.
