Need a much bigger picture of the dining space. What else will you have in here? Table and chairs? Do all of your plants have to go in here or can some go in other rooms?

Don’t know how much space you can dedicate/where your furniture will be placed and if willing to move some plants.

Generally speaking, similar pots are visually calmer and suggest a larger stand.

Place the larger ones in a corner and again, in complementary pots
