It really depends on the female, same as it really depends on the male. Some males CAN be kept in community tanks...though it appears that yours can't.
Most females aren't really as bad as the males. In fact, some aren't bad at all. Looking at your tankmates, I really wouldn't add any to that particular tank. Bettas and Guppies make poor tankmates, and that includes female Bettas combined with Guppies (I know, I tried it, and my male Guppy had a tail-ectomy). Also, my Mollies (tried that, too) were extremely aggressive with one of my female Bettas, and I found the female Betta cowering in a corner with a female Molly pecking at her.
If you want a female community tank, it can be quite lovely to have about 6 female Bettas in a 10 gallon tank, with plenty of caves and plants for them to hide from each other if necessary. Female Bettas are aggressive within their own species. It is a bad idea to keep two of them together, because one will assume dominance and make life simply miserable for the other female. In the case of three females together, two will often gang up and pick on the other one. Four or more females tends to even out the aggression, and establish a working hierarchy so no one female gets picked on. I have noticed, however, that in groups of 5+, and especially 6+, no fin damage is ever noticed after the initial meet, greet, and find out who's the biggest, meanest girl. Once the hierarchy and dominance is established, life goes on its merry way, and the girls will butt up against each other during feeding time without taking offense. However, there can always be this one, super-aggressive mean female who must be housed alone.
