I don't claim to be an expert so I'm just speaking from experience. Puppy's need to be walked several time's a day, as their bladders are just a wee size yet. Also puppy's have tons of energy and need a lot of exercise.
If the puppies are with the mother then you should keep them with her until 8 weeks of age. The mother will instinctively wean the puppies on her own, but you may need to help her by removing her from the puppies. The puppies can technically be taken away after 6 weeks, but the longer the puppies are with the mother the better because they will learn from their mother.
Puppies need to be taken out after they ate because they digest food very quickly, but older dogs don't need to be taken out every time after they ate.
10 times a day
That depends where you got the puppy from. If the puppy is from a breeder, the breeder often breeds dogs in her own home. If you got the puppy from an animal shelter, the puppies are often taken from puppy mills (places that breed massive numbers of puppies under bad conditions) or found on the streets. Puppies from puppy stores are usually purchased from breeders.
At 12 weeks old, puppies typically need to pee every 1-2 hours during the day.
two months the puppies should not need there moms
Depends, was it born at some one else's house? Then you can get it right away. If it was born at the vet's, then it depends on how many precautionaries need to be taken.
8 months minimum
No more than other puppies
Puppies are the young of dogs. They are helpless and need care from their mom.
No, not unless you anticipate complications. However the puppies will need their shots so you do need to be registered with a vet.
No. Taking a puppy away at such a young age would be severely detrimental to its health and mental development. Puppies need to be fully weaned, and gone through the socialisation stage (which happens around 6 - 8 weeks) with their own littermates, mother, and humans before they can be taken away. Puppies that have left before this time will most likely have socialisation problems later on.
