  Yes, it's very possible, and each private key can have it's own
different passphrase. GnuPG knows what key to use to decrypt each message.

  Well, the advantage is you can decrypt all the messages encrypted to
your different keys without having to switch from one keyring to
another. The disadvantage is if your hdd crashes, all your keys crash
together. Of course, the idea is to have a backup.

  I started making 1 different key pair for each one of my email
accounts. But at some point, I added more UIDs, so currently 2 of my
email accounts can use either 1 key or another one. The remaining email
addresses are still "isolated". And I keep all those keys in the same
keyrings, and I manage all the email accounts from the same email client
(Mozilla Thunderbird). My TB is configured to use 1 key when composing
messages from 1 email account, and other key for the other account, and
so on.

  Best Regards
