Glass Wall
Transparent Glass walls can be used as "bulletproof glass" bacause its like a much larger version of the glass panes. Are crafted in the same fashion as glass pnes but at the bottom of the crafting table and panes at the top.
Obsidian and Bedrock wall
Same as the fences: can both be crafted and do neither connect to other walls nor to fence gates
Colored Glass Walls
Work in the same way as glass walls
Obsidian and Bedrock wall
Crafted in the same way like stone fences (yes also the bedrock one). They are special because they do not connect to other fences.
Stone Fences
They are crafted like regular fences just with their material each and stonesticks crafted with 2 cobble or cleanstone above each other.
Iron Fence Gate
Works like iron trapdoors or iron doors. They do only open when powered by redstone. crafted like wooden fence gates with iron ingots instead of the planks and stone sticks instead of the sticks.
Wooden walls
Can be crafted like any other wall. The problem with trapdoors is solved, that you craft trapdoors in the upper 6 crafting fields and the walls in the lower. Wooden Walls can be stripped
Additional Stone Walls
Can be crafted like all in minecraft included walls just with the respective material
