how do you tell which is male and female? I thought we had 2 male and 2 female guppies, but I think we have 3 males because their top fins all kinda look the same, kinda like a ponytail where it just kinda hangs, and the one i think is a female, her top fin is just stiff. Is it the same with mollies?

The anal fin is the one at which you must look. The males have swordlike extensions called gonopodia (singular, gonopodium) and these are used for fertilization.
For the most part, but you can't completely rely upon that as an indicator. Bettas have gone the same way, where females are now becoming nearly as attractive as males.
guppies are still ok. females are generally larger and less colorful on the body.
as for betta, female bettas and betta ST look almost same. i've not come across any females that are fancy, other than the super-fancy female bettas i saw on internet.

The gonopodium is the diagnostic feature. Not all livebearers have secondary sexual characteristics, so it's easiest to learn the method that works for all.
i recently got some new guppies, and i was amazed just how much the females look like males these days. but the body of the females is alot more broader and fuller than that of the male...but the best method is, as mentioned, the best method is to look at the gonopodium.
Only Poeciliid livebearers - i.e. most aquarium livebearing species. Egglayers fertilise externally as a rule and have no fin modifications of this type. Even other livebearing families (more rarely seen in aquaria) have different modifications.
Come to think of it, IIRC, those of the Anablepidae and Half-beaks are pretty similar.
