The type on the bottom left are Cyclopoids of which Copepoda is the class name. Most of what you now have in the jar are likely copepods. Without adequate suspended particulate food most of the filter feeding Daphnia types probably have died. Many of the copepods are predatory grasping feeders and will usually live longer in a jar than the Daphnia types. The current community in the jar could be quite a bit different than the one you originally collected.
