Should i get more guinea pigs or not?

Looks like you, (a), need some serious counseling, and (b) are not taking care of your guinea pigs properly. Even though they are cute, small, and fuzzy, they need a lot of care. They are also sensitive to heat. Were their water bottles clean? Were they fed every day? I beg you; please do some research on guinea pig care before you get another one. Animals shouldn't die because their owners lack responsibility.
