Shot and Slug
Depends on what it is choked.
Any non rifled slug. However for best perfomance you want a "saboted" slug.
A slug is a mollusk like a snail, if you mean a slug like from a shotgun about length of shell, slug can also be slang for bullets which can be literally any size up to max.
A single, non-rifled projectile shot out of a rifled bore shotgun (specifically a slug gun).
Depends on what gauge the shotgun is.
Yes: A Remington 870 shotgun with a modified choke will shoot any commercial shotgun slug.
