Good for you in taking them in. It depends how long they have been together as to what has been going on. In poor conditions females may not come in to heat and therefore not mate or they can resorb pups if their body feels it will not cope with pups.
The hamster with a cloudy eye likely had an injury which has resulted in the clouding. It will probably be able to see normally from the other eye if it isn't cloudy.
I hope she isn't pregnant but if she is I'm sure you will cope just fine and so will she.
Good luck!
