No, hamsters have better vision in the dark because they are nocturnal
Cover up your hamster's cage during the day and make it light during the night.
hamsters prefer to be in darkness as they are nocturnal but if you need a light on near the cage then it should be dim and not too bright!
They need a weal because they run 3 miles at night.
no they do not need light they need sleep.
No, they are nocturnal and don't need light for sleep.
If you don't mind the possibility of the hamster waking you up by running on its wheel or doing other activities during the night you should be fine. On the other hand if you are a light sleeper and need sleep you might not want to do this. Yes though, it is probably fine to let your hamster sleep in the same room as you.
Don't, the hamster may need water or food and spending the whole night in the ball with no access to either is not good for them. They might dehydrate and become sick.
