Drupal Form Checkbox having different name and id (of my choice)

$form['wrapper'][$unitClean.'_container'][$unitClean.'_cb'] = array(
                '#type' =>'checkbox', 
                '#title' => t($unit),
                );

I need name and id to be different for checkboxes, textboxes and select lists. Anybody with any idea?

I want to do this because I am populating multiple form elements in a loop, need to manipulate them using JS (in form of groups) and then process them on next page.
