haha this one 0_0 is a shocked face, the 0 being the eyes, and same with 0.0 and i think the last one is suppose to be -_- which means like.. omg seriously?

It's like a suprised face, the "0"s are the eyes and the "_" is the mouth, along with the "." being a mouth as well. For the last one though, it's like an upside down face with "_" being the eyes and "-" being the mouth. Hope that helps!
