Do I understand correctly, that you want to use multiple names for
one IP address? Then it is not possible to use different certificates,
because exim cannot know which name the client used for connecting
before switching to TLS/SSL.

With multiple IP addresses it is possible as the global
tls_certificate option is expanded. Use something like
tls_certificate = /etc/exim/$received_ip_address.cert
($interface_address in older Exim versions). You can also set and use
smtp_active_hostname.
