The male could fall into the "American Bully" category. These are basically dogs that are part APBT and part English Bulldog, Neapolitan Mastiff, Dogue de Bordeaux, your larger bred-for-looks-and-size American Staffordshire Terriers, and whatever else breed someone felt like breeding to.
Yes, your dog falls into the generic "pit bull" category. By this I mean, short fur, larger head, muscular build, and weighing anywhere between 30 and 130 lbs. That's pretty much what the general public and governments have deemed to be "pit bulls".
However, without knowing the exact lineage of the parents, the dog is basically a mixed breed dog. Remember, there is nothing wrong with the word "mutt".
Also, I thought you got this dog from someone in a parking lot or something? How would you have pictures of the parent dogs? I'm confused.... (going back to reread)
