Yes it is. See the dtml-in options in the dtml reference for "batching" to
do so. (Zope Online Help in your ZMI -> Zope Help -> DTML Reference)

Do you mean "Database connections"? Then the answer is "no". If you think to create a
second query (Z SQL Method): for sure. If you need deeper help on the "database access
object" try to post your questions using more well known terms.

No problem, but try using the Online Help of the ZMI more often, you will find
a lot of useful informationen e.g. about DTML there.
