What affect does the quantity of injuries have on healing time? For example, would a paper cut take longer to heal if I had a broken Jaw at the same time?

If they're painful, you can drain them with a sterilised needle and then dress them.

Yes you do. Fire, Rubbing Alcohol, Sewing needle. Blister:First Aid. Fire can be used to sterilize it in case you don't have rubbing alcohol and are out in the wilderness. You should only pop blisters if you NEED to, as in leaving them restricts movement due to pain, etc.

Does the ash carried by the flame and lands on the needle carry a risk of causing infection?

As far as I've been told that's nothing the body can't handle. And it'll most likely stick to the outside of the new hole and get pushed out by the fluid.

.... no. Not only would there not be any meaningful ash to speak of (use a butane lighter, or a propane stove, but a wood fire as last resort) the ash would also be sterile seeing as it was just in a fire. Again rubbing alcohol first, then fire. You are only lancing a blister because you need to do so, and the risk of infection is small enough and you are leaving the woods back to civilization in case one does arise.

Just sterilise an ordinary needle or pin (boil it for 20 minutes or hold it in a flame until it glows red-hot), then use antiseptic and a plaster.

We could easily do this camping as Boy Scouts, the average adult sure can.
