Update [April 20, 2017]: As you already know, the Nine mail app supports multiple accounts. But, unfortunately, until the recent update, there was no way to change the signature for each account individually. However, thanks to the update that has pumped the version to 3.2.5, it now introduces multiple signatures. You will find a “signature” setting in each of your nine mail accounts.

To change the signature for each account separately go into Nine mail settings, then select your account and tap the “signature” option.
