How to redirect the users to a different form with the conditional logic?

Who do I create a logic rule if I want one form to then feed into multiple.

I.e. a general form asking what type of form you want. They then select the form that takes them to that specific form 

If I understood you correctly, you want to redirect your users to a specific form based on the option they selected on your first form.  

You can achieve that with the 'Change Thank You page' conditional logic. Inside of this guide, you can find how to do it:
