Camunda: Angular module implementation?

I have several questions about angular implementationn in camunda projects i have already read documentation but here are several things which are steal not clear for me:

  1. will i have to generate angular modules inside my maven project in order to parse json array data and use ng-module for transfering this data inside my table ( in camunda embeded forms)?
    2.how should i implement pipes and directives?
    3.how should i generate multiple form instance after form button click?
