Before getting a puppy, it is important to know what behaviours to expect. Whining and crying is very common puppy behaviour. It's natural way of communicating for young pups. How much a puppy cries and whines depends on the puppy. It is very important that puppies stay with their mothers for at least the first eight weeks of life. If someone is trying to sell you a puppy younger than that, don't fall for it! You're not dealing with a good breeder and could be faced with raising a puppy that did not receive critical teaching and information from its mother and siblings. I've seen it with my own eyes that puppies that are separated from their mums too early develop anxieties.
