Can you post a photo of your tank? I am wondering how much decoration is in there and how it is set up... With mollys, aggression levels can usually be worked out with appropriate decor (and enough of it) in the tank, especially plants (live or fake no matter).
I would not suggest mixing 1 single female molly with all of those male mollys, not because of aggression but because of breeding habits. She wouldn't stand a chance with that many males. When it comes to live bearing fishes such as mollys, platys, guppies, swordtails, etc the appropriate ratio is 2 or more females for each male, and this only if you are prepared for the massive breeding it will bring.
Aggression levels will vary from fish to fish, each has its own individual personality. While some generalization can be done according to species and aggression levels, it still boils down to each individual fish. Typically with mollys and platys aggression levels are generally low, and chasing is usually the result of males chasing females or staking territory and dominance over other fish, sex and species don't always matter when it comes to territory. With a photo of the tank I can probably offer you some suggestions on decor that will help tone down the aggression of your fish. Most fish can learn to be compatible if the tank is large enough and set up to accommodate each fish's individual needs.
As an example, I have a pair of breeding angelfish in a 65 gallon tank with 1 neon tetra, and they live peacefully. The average angelfish will eat neons, and this is not something I suggest an inexperienced fish keeper try to accomplish... but with enough plants and rock work to accommodate both fish species, they live peacefully together even during the spawning of the angels. In order to keep this situation peaceful I will have to upgrade the size of the tank as the angelfish grow to adult size, and maintain the heavy amount of plants and rock work in their tank. Most people are not content with a 65 gallon tank with only 3 fish... and that is where the issues would begin.
So can these things be done? Yes. But only if done the right way.
