That depends entirely on the functionality of Mysql, about which I know
very, very little.

The way to do this is to use the "queries" option instead of "query".
This allows you to specify a list of queries to try in order.

Exim cannot do that kind of thing for query languages. It requires too
much knowledge of the query language, which is why I left it to admins
to set up for themselves. (In principle a query language could have
inbuilt features for this kind of thing.)

Of course.
local_domains = mysql;select whatever from whatever
See the definition of "domain list".

Not necessary for lookups.

I don't fully understand your question, but there is no such variable as
$subdomain. However, you could use a regex to split up
"test.nildram.co.uk" into separate parts if you wanted.
