If you manually log in to those servers using Putty, click the "Yes" button on that dialog, Putty will cache the server key so those dialogs will not pop up on subsequent connections (unless you reinstall ssh on the server or change the server's key)

You can use plink, a command-line version of Putty, that should not pop-up these dialogs (or use openssh) I haven't used plink.
