Hi Ramon,
I’m not sure I entirely understand your questions- if you’d like the ability for your users to sign up and pay for events, you’ll want to purchase either WooTickets.
Generally when a user purchases tickets the only information needed is their contact and payment information. It may be possible for you to include addition questions there, but that would likely be more on the WooCommerce side of things and may also require some customization or development. I recommend that you explore the WooCommerce support materials to learn more about the possibilities there.
Cheers,
Leah
