You often can slip a flat prybar (the end on the right in the pic) http://www.hor-i-zon.com/catalog/images/PC58.jpg under the shingle and on top of the nail head and hammer the exposed bar which will push the nail down
but...
the nail may have popped because the wood was not solid enough to hold it. It will eventually pop again.

Since the nails are out already, just use black roofing cement on the holes. Where you popped the shingle up, lay down some roofing cement to reseal and hold the shingle down. $2-$6 depending on what you get.

Well, you solved one symptom, but you have potentially created a bigger problem. The nails are the only things holding the shingles in place. If you remove them, what's to prevent a strong wind from lifting the shingles off of the roof? If you use any sort of adhesive - roofing cement would be the first choice to glue the shingles together and fill the holes - it won't fasten the shingles to the roof sheathing.
The first thing to do is to investigate why the nails were popping up. Can you get into the attic under the area where you are having the problem and locate the missing nails? How thick is the roof sheathing and what material is it? Age of the structure and shingles?
Probably available in convenient caulk tubes, too. Start at the top of the roof, and work down. If you go from bottom up, you'll be kneeling in the earlier work. Knee pads, sneakers, good ideas.

After you apply the roof cement, I would put a brick or something heavy on top of the shingle(s) to hold them down for a couple of days until things set up. If you are in the northern USA, the days are short and cool and the cement will take a couple of days for the adhesive to evaporate and the shigles to be firmly adhered to each other. Be sure to put cement everywhere you removed a nail so there are no leaks.

A strong wind can take off shingles that are nailed with the full complement. Why would you believe that removing nails from a 2' x 2.5' area wouldn't compromise the shingle attachment? The wind doesn't tug the shingles in plane with the roof, it pulls them up a bit, the wind gets under the lifted edge and you now have a shingle free area. Removing a single nail increases the odds of that happening. If you are in an area that doesn't experience winds greater than, say, 50 mph, you might be okay. Any greater than that and you are asking to have a roofer come out during a storm. But it's not my roof, and I'm not the one taking the risk. Your house, your call.

Roofing cement is available in tubes that fit a standard caulking gun.

Now you know why plywood is so much better for roof sheathing. Subs in the roofing business have told me horror stories of 7/16" OSB (or maybe less) where the roofing nails have popped out chunks of material underneath, leaving very little of the crumble board to hold the nail. If this is your case, plan for a very expensive roof resheathing and reshingling after some future wind storm. Good luck.

You can generally buy quarts as well as caulking tubes of "plastic roofing cement".
