Guppies and mollies can interbreed so it's best not to keep them together unless you have all male guppies and mollies

They can breed, but the offspring aren't usually viable, and almost always sterile.  The biggest concern is that if the female is the guppy it can cause more serious concerns.  The guppy being so small, it can actually die while being pregnant. (Just as breeding a horse and a donkey makes a mule, the horse needs to be the female - to handle the size of the colt.  So it is with molly and guppies.  The molly would need to be the female.)
 
Platies and Swordtails can easily interbreed and make viable offspring, that are capable of reproducing.
 
 
The easiest answer is to keep only males and you don't have to worry about any of this.  The male guppies are always the more colorful...
