User Import: Possible to use other variables in the user notification email?
Probably not easily an existing request in the issue queues shows people want to add fields from the Content Profile module on the 6.x branch of this module:
https://www.drupal.org/node/1060394

There is a small patch in that issue that adds custom profile fields into the allowed list. The tokens would be in the same format as the given !username examples, eg !field_schools_owned_zone_1 for 1 of your fields.

Until that patch is added to the version of the module you're using you'd have to apply or adapt that patch to your site.
