One recurring aspect of fictional vampires is that they are all "immortal", except that some can lose their immortality (be killed) by various methods. Some are required to feed regularly to live and move about. Otherwise they die or become dormant.

It depends on the type of vampire and how often they feed. And how they feed.
Some are immortal in body, which is rare. Some are immortal souls which are reincarnated. Some have human bodies, but live longer than would be expected (these are usually the ones that unsuccessfully changed into vampires).

Vampires don't exist and they are dead so they don't "live".
No, vampires don't all live the same amount of time due to the fact that they are made at different points in time and they might be killed before the due ending
Yes, generally.
well it depends how long you live for...... sooo no
As vampires are already dead (no longer living) your question is an oxymoron and has no valid answer.
Vampier bats live 3-5 years & there has never been a vampire.
No they don't live for the same amount of time because all vampires are not the same.
no they are immortal
No.
Until they are destroyed, yes.
No, the lifespan of vampires is generally extended compared to humans due to their supernatural abilities and immortality. The specific lifespan of a vampire can vary depending on the lore or mythology being portrayed.
According to most literature and films, vampires are immortal and as such can live as long as they are not killed in some way eg. by having a wooden stake driven through the heart or excessive exposure to sunlight. However it should be noted vampires are mythological creatures and as such do not exist in real life.
