Answer 1

Copy all content from customer-form.tpl to identity.tpl and registration.tpl and then make your modifications.
As advice, you should make some changes in corresponding front controller and model object too, because it has validation based on current customer-form.tpl fields. Code should be something like this:
{render file='customer/_partials/form-that-you-want.tpl' ui=$form-that-you-want}
Good luck.

Answer 2

In PrestaShop each page has a unique value and this value can be fetched using the following code:
$this->context->smarty->smarty->tpl_vars['page']->value['page_name']
You will get a different value from above variable on Identity and Registration page, you can pass the value of above variable through Smarty and add a condition in 'custom-form.tpl'
