Yes, if you're talking about the traditional vampire, as they don't need to breathe.
Actually they do breath - their method of processing energy is much the same as that for living people, metabolizing oxygen and organic fuel. Oxygen from water however isn't as effectively obtained by lungs as it is by gills so a vampire underwater isn't as active as one in air. A vampire however cannot be drowned. He may be rendered comatose, but as soon as he gets back to air he will revive. Certain vampires have been known to be buried for hundreds of years and still be perfectly active when they are freed.
Kind of like a cave. Probably forever.
ALL animals must eat to remain alive. If a bat (or any other animal) does not eat, it will die of starvation.
It usually lives underwater!!
no idea
A vampire bat can typically survive for about a week without feeding on blood. After this time, they become weak and may die if they do not find a blood meal.
no
Cockroaches can be terrible pests, and even worse if there is an infestation. A cockroach would not survive being hit with a baseball bat.
with no food, probably only a few days. some thing like mice. probably one week.
Fruit and nuts

There are several that are recognized by ITIS: the Southern long-nosed bat is Leptonycteris curasoae, the Greater long-nosed bat is Leptonycteris nivalis, and the Lesser long-nosed bat is Leptonycteris yerbabuenae. Similar species are the Minor long-nosed long-tongued bat Choeroniscus minor, and the Puerto Rican long-nosed bat, Monophyllus frater.
