For pain control and to stop bleeding you can use a cold compress (a facecloth with an icecube can work) on the sore or bleeding areas.
You can use Neosporin or Triple Antibitoic ointment on the spots where there are cuts.
If you happen to have any of the powder used to stop bleeding on nails that are cut too short you can put a bit of that styptic powder on the bleeding area to help it clot. It does sting a bit though.
It is absolutely normal for an adult dog to warn off a pup who is being rude about approaching food items. Puppies learn manners by the adult dogs correcting their behavior. Had the adult intended serious injury the pup would have been badly hurt not just slightly cut. Sounds like the adult may have done a corrective snap with a bit too much force for a baby pup.
Best option while introducing the pup is to remove the 'bones of contention' by picking up all real food treats for now and confining the real food chew items to being available only when the dogs are in crates or the pup is confined away from the adults with his own chewie. As the pup learns more respect and is old enough to understand the warning signals of the adult dogs you may be able to reintroduce the chew items to a less restricted use.
Hope this helps you!

Pups usually heal pretty well.
You just don't want to get ointment in the eye as it will sting.
Sometimes the nose scars and sometimes it fills in black (or red or blue as the case may be) over time so it may start out pink and then fill in as the pup grows.
One of the big problems is the breeder let this puppy go home with you two weeks too soon for it to have learned social skills from mom and siblings. Your adult dogs will not be as kind in correcting the pup so it learns the social signals as the mom and siblings would have been. Pups really should not go home before 49 days (7weeks) at the earliest and 8-9 weeks can really be better.
Thanks for the above accept!
The cold compress over the bridge of the nose should help with that.
He might have a bit of a crush injury to the nose area which is bleeding. Or the cut up by the eye might be deep enough to go down near the nasal area and drain there.
Plan to have your vet check him out well.
He should recover from this with care. You are right its a bit like a broken nose but you can see a picture here to see how complicated the nose area is
