how can i add custom fields with registration form?

Hi i am working for a site which will include premium membership option & i found WPMUDEV membership. i thought it will be working perfectly but when i am trying to use custom registration field i cant see any option. I have attached the layout how & what fields i want for registration form, also you will notice i have designed custom login so i want to know is that possible with this plugin if how? Any plugin or code?

Thanks
