How can I use the Commerce Paypal module module without the Commerce module?
Commerce Paypal has the following dependencies:


commerce
commerce_ui
commerce_payment
commerce_order


Installing/using Commerce Paypal without Drupal Commerce isn't possible; it's a supplemental payment module, and requires Commerce's API to work.

You may instead be interested in something like Webform Paypal


  The Webform Paypal module sends the user to Paypal to complete a payment whenever they submit a webform containing the component on your site.
