to tell you hamsters only like each other when they want to have kids
There is no way to tell if it's a male or female until it's an adult. Even then, you need to have a biologist check for you. Male frogs sing each night to find a mate, but there is really no way to tell!
You can never really tell when they're very young. Wait for them to mature first.
Babies (both male and female) will be significantly smaller than their mother when they are at the age for removal (3 weeks). If you have waited too long and they are all the same size, and assuming they all look like their mother, you may never be able to tell. But if you've waited that long, you will probably have a new litter on the way for each female baby - hamsters WILL inbreed between siblings.
Male guppies are colorful and females are not. They are usually white or clear in color.
