Two notable features that mammals have in common are that they all give birth to live young and they all have hair. Another thing that most mammals have in common is that the females make milk to feed their young.
Birds and mammals are closely related. There are many similarities - both are vertebrates (have backbones), both are endothermic (warm-blooded) and both breathe oxygen from the air.

Platypuses (and echidnas) are members of a quite different order of mammals known as monotremes. They are egg-laying mammals, but still classified as mammals since they nurture their young with mothers' milk. They also share other characteristics with mammals, such as being warm-blooded, having fur, skin or hair, and breathing via lungs rather than gills
Yes, mammals have different skin types. To cite one example, whales, which are mammals, live their entire lives in salt water. What happens to your hands after you've been in the water for a few hours? Whales don't have this problem because their skin is different than ours. The number of different skin types in mammals would depend on how you chose to classify skin types, and there are different ways of classifying skin. yes
