How do I create multiple forms? [closed]

Question

I want to create two modules for two forms. How can I achieve that? Namespace of both file will get conflict or not?

I am trying for this, and getting one error don't know its because of the two form or not.

Folder structure1:

modules->custom->amazing_forms
                   ->amazing_forms.info.yml
                   ->amazing_forms.routing.yml
                   ->src  
                       ->Formss
                          ->ContributeForm.php

Folder Structure2

modules->resume
           ->resume.info.yml
           ->resume.routing.yml
           ->src  
              ->Form
                 ->ResumeForm.php

Error:

InvalidArgumentException: Class "\Drupal\amazing_forms\Formss\ContriForm" does not exist. in Drupal\Core\DependencyInjection\ClassResolver->getInstanceFromDefinition() (line 29 of C:\xampp\htdocs\drupal8\core\lib\Drupal\Core\DependencyInjection\ClassResolver.php).

I have a question: Controller name should be Form only or we can use any other name for other modules as I have used above?
