It depends on the dog, its sex, pedigree, etc. I have two Jack Russells, unrelated to one another. My female is 6, and weighs about 14 pounds. My male is 8 and weighs about 20 pounds. Both are considered by my veterinarian to be a healthy weight based on their size. If I remember correctly, they didn’t grow much in height from 9 months onward, but seemed to “fill out” until they were about a year and a half old.
Jack Russells on average are 15 pounds when fully grown, so somewhere between 10 and 15 pounds is likely acceptable. Jack Russells are traditionally bread to be lean with visible muscle tone.

Its almost impossible to find an average weight for puppies because there are so many factors to consider like the size of the parents, the size of the litter, the size of the puppies within the litter, the sex of the puppy, how quickly or slowly it develops….and so on.
If your puppy is active and has a clean bill of health from the vet, then their weight is most likely appropriate for their age and size. If your afraid your dog is becoming overwheight, it might be because he/she is getting to the point of starting to fill out more.

Don’t suppose anyone on Earth knows the answer to that one. Average weight isn’t really relevant for any breed at any age - what’s important is the shape of the dog. Get a vet to check she’s at an ideal weight if you’re worried. her ribs should be easily felt but not visible, spine to visible etc - bit of extra chub on a puppy is OK but if she’s waddling around she’s too fat!
