Staffordshire bull terriers do shed their hair, but it should not be too much shedding, if it is, there could be a problem and the dog should go to the vet.
Yes, the Yorkshire Terrier is a small dog, so having a small litter is common.
A three month old Staffordshire is still young, and it is normal for puppies to tire easily. Puppies have short bursts of high energy, and then periods of nap time. The dog is likely getting hot during play and this causes the panting.
That is not normal. As a matter of fact, I don't know since this condition I have never seen it. The best bet is to visit the veterinarian.

Hiccups are very common in all puppies and are actually quite normal. Puppies get hiccups when they eat and drink as they tend to ingest large quantities of air which then triggers hiccups.

The number of pups will vary regardless -- but PLEASE do NOT cross-breed these dogs! Breeding is a serious venture and purebred lines should be respected for the best interest of the dogs and the breed. Poor breeding results in weaker dogs with more medical problems, and mutt pups are denied official recognition by many organizations and venues. In short, it isn't fair to the dogs in question, nor their respective bloodlines.
