New born pups need plenty of rest. I know its hard to keep your hands off them because they are so darn cute. It would not hurt to pick them up once in a while so they get use to humans, but mostly you should let them rest. After their eyes open and they start moving around you will have plenty of time to play with them. They themselves will let you know.
some people say the mom will reject the puppies if you hold them after they are born but.... that's not true,only the female cat's do that kinda selfish stuff!
When the newborn puppy is strong enough to hold it's head up by it self,then you can hold it!
You can hold them as much as you like. If the puppies are being raised without their mother they are lacking the physical contact they would normally have with her. You will be replacing the mother so more is better.
By the time they are 4 weeks old, the newborn puppies are usually old enough to be smothered.

Newborn rottweiler puppies are at risk of problems common to most newborn animals, including being taken away from the mother too early, which, if the puppies are not hand-raised, can lead to death. Other problems include birth defects, infection and injury. Newborn puppies must always be kept in a safe environment, as they are born blind.

You can touch the newborn puppies with your bare hands. It's not healthy for the puppies though even if the mother allows it.
Probably about 80%.

Yes they can smell where their mother is in the box.
