genetic hybrids, descended from parents with a slightly different number of chromosomes (different but closely related species)cannot reproduce. Examples of such hybrids are mules, ligers, tigleons, and seedless watermelons.

Millions. You just have to think in all the ants of the world. Only the queens and their mates reproduce. Most of the ants do not reproduce. The same is valid for the bees.

All living things have to... I know a few reproduce A-sexually without a mate, but that's still reproducing...

Lots of good answers here.
Just to add another one, many species are trying to reproduce but are unsuccessful due to human activity - either current or in the past. We are now dealing with a situation here where the resident population of killer whales is dying off...and the most popular reason is because of global warming and toxins in the water.
Sad.

all living things should be able to reproduce. if not, they wouldn't be named as "living things" cause one of living things' properties is "able to reproduce". but in some cases, a living thing can be sterile so they cannot reproduce.

Every species can reproduce.
While it is possible for you to find two different species who can interbreed (like horse and donkey), the offspring is not viable.
Maybe you meant to ask which organisms do not sexually reproduce?

None.
If a species didn't reproduce, it would no longer be living.
