I assume "non mammals" in your question means all animals that are not mammals.
There are over one million species of animals in the world that are not mammals. We cannot give an exact number because we do not know how many undiscovered animals there are. Mammals make up less than one half of one percent of all animals.
If you are asking, "How many individual animals are there on earth that are not mammals?" then no one can answer.

It depends on what you mean by non-mammals. If you are counting all matter as a non-mammal, then most non-mammals are not organisms. If you are counting a non-mammal as any life form or any animal that is not a mammal, then all non-mammals are organisms.

The echidna and the platypus are non-placental mammals. They are monotremes, or egg-laying mammals. Kangaroos, wallabies, koalas, bandicoots, wombats and Tasmanian devils are just a few other non-placentals, as they are marsupials.
What do all nonmammals have?
All extant mammals have some form of hair. No non-mammals have hair. Mammals have warm-blood. Non-mammals, with the exception of birds, are cold-blooded. Reptiles and birds have scales, but amphibians do not. Sponges do not have hearts or vertebrae. In short, there is not a whole lot that all non-mammals have in common, except the state of not being a mammal.
