By my math I hear that you are getting 5 colonies in one shape or form.
You also have approximately 20 drawn frames.
It would be my advice to spread them around (4 to each).
Your packages will appreciate immediate laying space.
Your nucs will appreciate additional laying space.
The results of both will be increases in population that will assure the best acceptance by all.
However, be warned. You are working on plastic. And some colonies can get a hair up their butt and avoid it all costs. So be prepared that if the frames do not appear to be gaining use within a week or two time, yank them, give them to those that do use them, and immediately introduce your alternative of choice.
If everything works well, you will begin to see all colonies equalize near the end of the first flow.
If not, then manually equalize to avoid summer dearth robbing.
You can avoid dwelling on cell size issue.
You are working on your desired cell size frames (so you won't inhibit your regression).
Acceptance issues arise later when established and 'beggers can be choosers'.
Keeping them fed and building comb will minimize how 'choosey' the bees can be.
But likewise, do not plug them with too much syrup.
