All groups of animals lay eggs. The one most commonly defined as non-egg-laying is the group known as mammals. Almost all mammals give birth to live young. The exception to this are the three species of monotremes, or egg-laying mammals, and they include the platypus and the two species of echidnas.
Within the other vertebrate groups, only the "Birds" are all egg-layers. There are some species of fish, reptile and amphibians which do not lay eggs.

In animals that lay eggs, yes, the female is the egg-layer.
Well, some types of birds lay one egg. But there are many animals that lay more than one! Like snakes and lizards and, mostly, sea turtles. They can lay up to I think 200 or so eggs. I am not quite sure but I am pretty sure.
unlikely, but there in the same egg group.
Yes. Penguins are birds, therefore they lay eggs.
