Yes. However, side by side double barrel shotguns are built so that line of sight from the two barrels meet each other, and cross- usually at about 35-40 yards. This means that a slug fired from the right barrel will go the the left of the aiming point beyond that range, the left barrel, slug goes right of the aiming point.
Most shot guns can handle deer slugs.
If the Stevens double is a modern gun in good condition you can shoot slugs in it. Some double guns may tend to "cross shoot." You'll just have to try it and see. Keep the distance short, to 30 yards or so.
Definately not. I can't think of any offhand that can, but if it is not marked on the barrel then it cannot shoot them.
Have a gunsmith check the gun before you fire it.
Depends on the ammunition. Rifled 12 gauge slugs are accurate to about 150 yards
Only use or shoot cartridges that have the same caliber as the one marked on the barrel of your firearm.
Yes. Be careful if it is choked full.
DO NOT ATTEMPT TO FIRE MODERN AMMUNITION until a good gunsmith checks it out.
