Apparently they were all remarkably beautiful females!

Since we know practically nothing about the characters, I don't think we'll ever know if and how that's significant. I suspect that the similarity of the names was deliberate, and that they were chosen for their pleasant effect when spoken - meaning being a minor consideration in Hobbit naming convention. Tolkien may have borrowed an idea from Anglo-Saxon naming convention, in which names were chosen in part because they alliterated with other names borne by members of the same family (usually fathers, grandfathers, etc.), making them easy to fit into poems recording important peoples' ancestors and easy to remember when the poems were recited. Although these names don't alliterate in the modern sense, they are memorable because of their shared components.

Belladonna and Mirabella are both botanical names, the former for Deadly Nightshade as Guinevere pointed out, the latter for the Mirabelle plum (Tolkien preferred Italian to French, so it's not surprising that he'd use an Italian form). Donnamira is the odd one out, since it doesn't refer to any common plant species.

I must admit to a mistake above: mira tends to mean 'wondrous' or 'marvellous' more than 'remarkable' (Lat. mira, mirus). Although that might mean that the sisters were all beautiful, knowing Tolkien's sense of humour they could just as easily have been extremely plain.
