It depends how long he's been hibernating. If you just caught it, then put him somewhere like under your shirt, somewhere warm and make sure to warm him up until he wakes up and seems active again.
If it's any later you can't wake him up and, well to put it bluntly he's going to die. I'm sorry.
give it warmth

Most animals will not wake up if you touch them or move them around. Hibernation is not like normal sleeping. But don't try your luck! Some animals, like bears, go into a temporary sleep. They will wake up very quickly if they are disturbed. Don't bug sleeping animals!!!
Make it nice and warm and cosy and try to feed it some food. This may (note I said may) help it wake up.
No, the whole metabolism shuts down to almost nothing.
Possibly, I know that if a bear does not eat enough it can wake up from its hibernation to eat.
