Brick walls allow the Blue Legion, Skeleton Commando, Necromancer and Paladin to spawn. I think it also allows Cursed Skulls and Dragon Skulls to spawn in Pre-Plantera.They look like, well, bricks.

Tiled Walls allow the Hell Legion, Diabolist, Tactical Skeleton and Giant Cursed Skull to spawn. (And Blazing Wheels in Pre-Plant.) They look like diagonal walls.

Slab Walls allow the Rusty Legion, Ragged Caster, Skeleton Sniper, Giant Cursed Skull and Spike Ball (pre-plant) to spawn and look like smaller bricks compared to Brick Walls.

Bone Lee spawns in all walls.
