Actually, there is only one which definitely needs replacing because it is rusting underneath externally.
Others seem OK at least externally, though the large one in the living room has needed bleeding a couple of times, so I assume it is rusting internally. I may be wrong, but when I last bled it there was a distinctive smell from the gas escaping.
I might try that little trick of collecting some gas in an upturned container and see if it pops!
