Wow, kudos to you for all the research you did before hand. You picked out some great breeds. They should all get along fine aside from the normal pecking order. One thing we do is keep a flock block in the run so they can peck at it. It gives them something to do so they don't get board. Best of wishes to you and the new chicks.
I think your hens will get along fine--I've raised several different types of breeds together, and have never had any problem. Good luck with your chicks! They sure are cute.
