Try not to stress too much. Even if these ones don't make it, you have a male and a female guppy, there will be more fry for sure.
You might want to consider what you're going to do long term though. With guppies, it's recommended females outnumber the males because males can be sex pests, and if they're constantly chasing a female, she can become exhausted to the point of death. Endlers can interbreed with guppies, and it looks in that photo that the male endler is chasing the female guppy. If that one female is being harassed by the male guppy and the male endler, and also doesn't have much in the way of plants to hide in either, she could be in trouble. So it's worth considering rehoming the female, or adding more females. But more females also means more fry.
