Hair usually grows on hamsters 10 days after birth.
2 to 4 weeks.

The hair that grows on a baby whilst it's still inside the womb is called lanugo.
Yes, hamsters have hair.
they normally start developing hair around puberty at around 16 years old
Baby hamsters are called "pups".
Baby hamsters are born pink, hairless, blind, deaf and helpless. They grow really quickly, and start to grow hair (you can already make out the pigmentation on their pink skin before their hair grows in some cases) around the time their eyes start to open. They don't walk too well then, but they can drag themselves along, and the mother is constantly picking up stray baby hamsters on the other side of the cage and bringing them back to her nest. After that they grow more hair, grow bigger, don't look so squint-eyes anymore and their outer ears are more noticeable. By then they can walk and are starting to eat solid food and drink water.
No they won`t.
No the first two weeks the mother takes care of them. When the hamsters are starting to grow hair you can either sell them or take care of them
If they are hungry and are annoyed by their siblings
Hamsters can eat baby tomatoes, its good for them
All baby hamsters are called "pups".
