they look to be really poor quality cherry shrimp. probably males by the pics. the one on the right either has a really bad bacterial infections or okolona parasite that turns them white. if its okolona parasite it will live just fine but can be passed in breeding to the offspring. if its bacterial it will die from it and can be passed to other shrimp if they eat the infected shrimp. keep a close eye on it and make sure none of the other shrimp start turning white like this.
