The saddle needs to fit BOTH horse and RIDER. Depending on the seat of the rider a typical pony saddle would have a 10 to 14 inch seat. You will need to have a longer girth on a smaller saddle.
It should unless the pony has a very large head. Cob sized tack is similar to Arabian size.
It could but it'll depend on how broad the ponys' back is.
There is no 'one size fits all' for specific breeds of horses and ponies. It would be best to measure the pony for a saddle or have someone more experienced , like a saddler , try to fit the pony for a saddle.

It sounds like you may have a 'youth' saddle. A pony saddle is pretty small and you would be able to tell right away that it was meant for ponies. A youth saddle is meant for that in-between stage when the rider has outgrown a pony saddle and is still to small for a full sized horse saddle. To find out you can measure the saddle's tree. Take a tape measure and start at the pommel and run the tape to the cantle. This will give you an idea of the size of the tree which is what the entire saddle is based on.
To determine the size tree of an English HDR Pony Pro 2004 R 01 P saddle, you can look for a size label or stamp inside the saddle, typically found on the flap or under the saddle's skirt. If no label is present, measuring the width of the saddle's gullet (the channel underneath the pommel) can provide an indication of the tree size. Generally, widths are categorized as narrow, medium, or wide, with specific measurements corresponding to each category. Consulting the manufacturer's guidelines or a saddle fitting professional can also help confirm the tree size.
It varies from 14hh to 16 or 17hh.
Depends on the weight and what excersise. Maybe one scoop if in heavy excersise and a relitvly large pony such as 14hh up. If below that but still in heavy work 3/4 scoop. If in light work a small handful even if heavy or large weight/size.
For a western saddle most pads will be about the same size unless it's for a pony saddle, which will be much smaller. English saddle pads can vary significantly. Since there are different types of English saddles the pads will correspond with their individual shapes. A dressage saddle will have a dressage pad, likewise hunt seat, saddle seat (with a 3 or 4 inch cutback). Whatever the size or shape, make sure that the pad is thick enough that it protects your horse's back and that it fits right so it won't slip or rub.
A 14'2'' horse would typically wear cob size shipping boots rather than pony size. Cob size is generally more appropriate for horses that are around 14-15 hands high, while pony size is more suitable for horses under 14 hands high.
If the size of their withers is the same, and the saddle fits them, you could use the saddle on both of them. If you do not know how to tell if a saddle fits, asking an expert you may know or looking for more information about saddle fitting may be helpful.
I would say 12.2hh to 13.2hh would be perfect size. x
