There is no room for more fish, and in fact the swordtail should be re-homed. This fish will attain 4-5 inches, and may reach 6 inches--if it is healthy. That is too much fish for a 10g. The profile recommends no less than a 30-inch tank length because this fish is an active swimmer and needs the space.
The molly is not a small fish either, with males at 3 inches and females possible of reaching 5 and possibly even 6 inches. To be healthy, they should go into a larger home too before very long.
