Find a comparable size screw and pop er in there. a wider screw is always better than a narrow however.
The scratched helmet may have been caused by accidental impact or friction. To repair it, you can try using a helmet repair kit or seek professional help. If the damage is severe, it may be best to replace the helmet for safety reasons.
The best way is to just buy new ones or get them out of another helmet
You can't repair armour. You can just buy a new set for another $650 (or $1000 including a helmet).

There are two exposed Phillips screws at the wheel well (and one behind the wheel well that attaches to the fender), and many square hole head plastic screws underneath the bumper cover across the front. I would check all of these first.
If you need to repair a slider that came off the rails. Then, use a screwdriver to open the charger. Find the missing piece and put it back on its rail.
Any motorcycle or ATV dealer would sell helmets. And many of the independent repair shops sell helmets also.
sew the laces together and stick the ripped bit with glue
That depends on what is broken, worn out, or missing. well when i pull the slide back to load it it doesnt load a BB into the barrel my guess is something is missing (its a pistol by the way, a double eagle,)
Check the instruction manual that should have came with the equipment itself. If there is no paperwork/instructions of any type the best options would be to consult Riddell Inc. or to consult with an area high school coach. If it cannot be fixed or if it is too much time to repair I would have a little fun and re-paint the helmet to match a favorite team and get the decals, warning labels, etc...Usually Ebay will have generic NFL and NCAA teams but as far as like local high school teams, it is best just to drop in and ask for the decals at the high school.
It is on rear of engine (where it attaches to tranny). Experienced auto repair personell should replace this part.
The plastic tank on the side of the radiator can be replaced but it would be quicker and cheaper to just install a new radiator.
