Newbie potting

Hi

I have a few small cherry tomato plants that i am going to move to a bigger pot tonight.

I have a large, long trough and i want to plant 4-5 plants.

I just wanted to check that i am doing it right

i was going to plant in this order

Tomato plant - 8-10inchs another plant - 8-10inchs Basil, then 8-10 inchs tomato then8-10 inch last tomato plant

Tomato--tomato--basil--tomato--tomato


is this going to be to much? Alternatively i was going to simply do one tomato plant - basil then tomato

i live in a flat so a pot is my only option

thoughts?
