3 ADFs and one betta in a ten gallon is pushing your bioload a bit, but it can be done. I usually say that two frogs are good in a five, and three in a ten, so you have a little bit of space to work with. Generally i suggest 2.5 gallons per male frog, and 3 gallons per female.
I have never had a frog in a sorority, but judging the way my sorority girls react to food being dropped in, the frog would likely starve to death in short order in a sorority. Best to stick to just a single male that can easily be distracted from the frog's food.
