When baby animals grow in eggs they are growing their organs that are needed. The eggs help protect the baby while it grows big enough to live outside the egg.

If the fish can find the eggs and/or babies they will eat them.
Insects lay their eggs on or near food, so when the babies hatch they wont be hungry and can grow faster. Insects want their babies to grow faster so they have a short period of many predators for their babies (which most carnivorous insects eat) and the adults have much fewer predators. a shorter period of predators for their offspring means they have a much more likely chance to survive.
Raccoons give birth to live babies, they do not hatch from eggs.
Some species of fish stay with their offspring, or babies. Most other fish will release eggs into the waters they live in, and the fish develop and grow on their own.
No, there will not be babies unless a male fertilizes the eggs.
