Wow, I'm so sorry you are dealing with this. You are right about setting yourself up a bit by getting two pups out of the same litter--just really a bad idea, unless you have a plan in place for personalized bonding and training until the puppies reach about 12-18 months old. So, to answer your question on your last post, I don't believe one month would be enough for the dogs. I would also not keep a puppy displaying that kind of extreme fear response.
The multipul bites to different areas really is a bad sign. But I wonder about one thing you posted about going out and holding the pups on their backs until they submit then you pick them up? How long have you done this and was this started after or before this puppy bit you? That actually might be the key to this entire thing depending on your answer.
Honestly I think your time and energy would be better spent on just one puppy to get an excellent guardian rather than one with such behavior issues....
