In the most general of terms, slug barrels are rifled and regular barrels are smooth bore. Both are capable of shooting slugs.
The amount of constriction at the muzzle
Slug guns have a fully rifled barrel like a center fire rifle. This helps improve accuracy. A regular shotgun barrel is smooth bore with different choke tubes for a specific desired shot pattern.
No
Yes, but, it is an exercise without a point.

Yes and no. The yes comes from simple fact, if the projectile can move down the barrel, it can be fired. I've seen .221 Fireballs fired out of a 7TCU barrel. The no is because you cannot do it well. In effect, if you shoot a slug down a smooth bore shotgun barrel, you will have little in the way of accuracy. Slugs should be shot from a slug barrel, and shot from a smooth bore.
That is correct.
Firing lead shot through a slug barrel will not damage the barrel. The rifling will distort the shot pattern and you will get less than desireable results.
