If your guppies are popping in there, that should be helping. lol
Slowly turn the temp up to 78-80 degrees. 80 is on the high end, so 78-79 would be good. Do it slow like the seasons changing over the course of a week or so.
You should only have one male per three females. Often the males will "Stick together" making sure the others don't go near the females. It can also lead to aggression among them. I would let go of one male, or get a couple more females.
Try feeding them live food if you can get it(blackworms, brine shrimp and the like), and food they have to work a bit for like algae wafers(just pieces at a time). Often when my girls are picking at the food, the males will try to mate with them. Live food, food they have to chase, often entices the males to chase and to breed.
Is your tank big enough for them(30+ gallons)? If space is not up to their standards, they often wont breed, and even if the males DO mate, females often wont drop or fertilize eggs. They get big, like territory and lot's of room to swim, so 30 gallons is a minimum recommendation for 3-5 swordtails, extra five gallons per or so.
Make sure they get enough to eat, food being more available means they have room for more hungry tummies.
Also make sure the water is nice and clean. Don't over-clean, just do a tad more than usual(30% once a week recommended, extra five percent or so if you want to help entice them to breed).
