Okay, this is just me talking about my werewolves from
Inhuman, which may or may not be reflective of the consensus of The Pack as a whole.

The nails toughen up, becoming thicker and more prominent, and the werewolf will grow fur over them. Other than that, there actually isn't that much of a change to the werewolf's hands unless they enter a full-wolf form. They tend to look more like claws, not because they literally elongate, but because werewolves have odd nerve and blood flow sensations that cause them to habitually hold their hands differently. Similarly, the werewolf won't develop pads on his hand unless he makes a habit of running on all fours, which will gradually cause his hands to callus and toughen up.
In a related note, this is what many werewolves believe to be the origin of the myth about the pentacle.
The five-point star, in their interpretation, is formed by the five lines of fur in between their footpads.
2. Feet change?
Actually, even less than their hands, at least physically. Werewolves don't literally have plantigrade feet. What they have instead is a plantigrade
posture (IE: with their heels elevated off the ground). Beyond that, the changes aren't much different from what happens to their feet; fur, tougher nails, and a gradual formation of footpads.
3. Torso change?
The biggest change, apart from the rapid fur growth, is in the spine. Since werewolves have tails, the werewolf's spine appears more prominent and doesn't "disappear" into the lower back. Beyond that, however, most changes are minor and negligible. Werewolves don't grow bigger or more muscular. They just look like it because of their change in posture.
4. Legs and arms change?
I know this is getting redundant, but until they start pushing towards the full wolf form, not a whole lot. Most of the apparent increase in size werewolves gain in their limbs is fur, and the rest of it is optical illusion from their posture.
5. What would it sound like? Ie what would you be hearing while shifting?
I know this is going to sound stupid, but. . . Like an old guy getting up and stretching on an empty stomach. A lot of popping, cracking and gurgling noises. Like the kinds we're accustomed to hearing from our own bodies, only more frequently and louder. You know, assuming you can even hear them over the werewolf screaming (the pain associated with shifting is, quite literally, indescribable).
