Multiple chalices next to each other??

[Borchers]

So I am dedicating an area to my system to my chalices which are all different types. I want to know can they all be placed next to each other. And how far away? I mean I have a 12x12 area for them. They are as follows

Bazooka Joe
Sour Apple
Bubble Gum Monster
Tyree Rainbow Oxypora
Golden Galexy
Robokaki
BPC Flamethrower
WWC Holograms
