A:
The delta variable is used several places in drupal to know which is which.
In this case with hook_block, it is possible to define more than one block. Drupal uses the delta to know what block it is currently processing.
$form_state is something Drupal uses to store data related to forms. Primarily the values submitted, but it can also be used for other things.
