Yes

It should not eat cardboard, this can clog up the intestines. but a little nibble there and a little nibble here it should not do anything to your rabbit no worries there
so their teeth stay short

No, they'll chew through it and escape.
Hamster can and will chew on a variety of objects. Hamsters are rodents and chew to keep their teeth short. Cardboard is a material hamsters seem to enjoy. Cardboard itself is not harmful to hamsters, but it is possible the ink or glue used in the manufacturing of the product's boxes may health problems. However, many people provide their hamsters with boxes for chewing, hiding, or entertainment with no adverse effects.
Not all hamsters are nice, at first he or she might bite you or nibble at your finger but if you get to know your hamster and your hamster gets to know you he or she will stop biting and will start to build trust in you. There are no other hamsters I know that are nice.
Yes they love to so they can make a hiding place.
Hamsters show affection by grooming themselves and others, cuddling with their companions, and squeaking with delight when interacting with their human caretakers. They may also nibble gently as a sign of affection.
Yes when they are wild. If they are domesticated not really unless its obvious like poison Ivy or plactis and cardboard even though they do nibble on it.
Any hamster can chew on cardboard. Just be careful and make sure the hamster is safe so he doesn't chew a hole out of it to escape or whatever :)))
