I can not see any performing at normal hash-rate, maybe I missed something.
First off, if you want advice that can be useful in your fault finding, a screenshot from ghash is NOT as usefule as a screenshot from your miners' Miner Status page, so if I were you, I'd post any number of the screenshots at your convenience.
It could be a power issue, it could be incorrect configuration of the pools or you may have duds on your hands (or a combination of all or none of those but another permutation of faults)!
