Yes. Many puppies experience episodes of hiccupping that may last several minutes. This is normal and will not last but a few weeks or months. All puppies have a characteristic odor to their breath that is commonly called "puppy breath." It is also normal and will last only until the puppy matures.
One of the characteristics of puppies is chewing. Puppies are trying their new teeth so chewing is a normal behavior. The puppy's baby teeth are present by about four weeks of age. They begin to fall out at four months of age and are replaced by the adult (permanent) teeth by about six months of age. Therefore, chewing is a puppy characteristic that you can expect until about 6-7 months of age. It is important that you do what you can to direct your puppy's chewing toward acceptable objects. You should provide items such as nylon chew bones, and other chew toys so other objects are spared.
