No one wants to touch this for some reason, chuckl
You need to be more specific about how big the roots of those plants may be, and how big those pots are, and it may be fine while they are small, but take into account how big the mature plant is. All of these things are going to affect what you plant together...

I usually have between 4-8 plants in each container, ranging in size from 12"-20", and between 2-6 different types of plants in each.

Just be sure that the plants in the same planter all require the same amount of sun and moisture.

always have a spiller, a thriller and a filler and you pots/containers will look great. And yes what Nancy said applies. no shade lovers in a full sun exposed container. to verify: spiller -something that will grow over the edges of your pot like sweet potato vine. the thriller-something bright and bold or tall and eye catching like a border dahlia or a grass. the filler should be something that will fill out the pot over time like bacoba or maybe impatiens. Anything that will stay bushy and mounded and you can pinch back. Hope this helps.
