Here is the Club Penguin answer: you can't, you can go to the Pet Shop and sometimes other penguins pretend to be little kids and you can "adopt" them.
Here is the real penguin answer: they have sex then the father penguin keeps the egg safe and warm on their feet with a skin flap going over it. During this time the mother penguin goes back to the ocean because having the egg made her lose lots of body weight. After the chick hatches, then the mother comes back. The father then has to hurry to the ocean because he has not eaten in a long time a will die if he doesn't get food soon. while he is away, the mother feeds the baby by regurgitating fish stored in a pouch in her throat. After some time {I do not know the exact amount} the mother and father leave their baby. For more information, watch the movie "March of the Penguins".
the humboldt penguin has about 10 penguins during its offspring
Penguins typically lay just one egg per breeding season, so the number of offspring in a litter for penguins is usually one chick. Penguins invest a lot of parental care in raising this single offspring to ensure its survival.

"Produce offspring" means, quite simply, to have babies.
Elephants and humans produce low numbers of offspring. Organisms that produce low numbers of offspring produce offspring that are most dependent on the mothers.
they like to eat chocolate ;)
only one at a time
No, organisms of different species can breed and produce offspring. Donkeys and horses can breed and produce mules but mules cannot produce offspring.
a group of similar organisms can produce offspring
no they produce penguins
It would not procreate (produce offspring), and if it were the last of its species, it would go extinct.
