Sadly no, you can't really mix and match to make up a school unless they are the same scientific name. A 10 gallon is pretty small for most schooling fish, especially the various skirt tetras. You could do 4-5 platys though. Get one of each color and she'll easily be able to tell them apart. Just be warned that if you don't get all males or all females that you'll have to figure out what to do with the babies.
I would avoid the usual types of danios, as they are much too active for a 10 gallon tank. GloFish Danios in particular are far too often marketed for the small tanks when they really need 30" of tank length minimum. You can use aqadvisor.com as a sanity check on your stocking plan. It's not foolproof and needs to be double checked with research and asking experienced fishkeepers (NOT your local fish store, their goal is usually just to sell fish, not have you keep them well), but it's a great starting point.
