Event Registration form

I'm trying to create a gala registration form where people can select different Sponsorship levels or individual ticket but once they select the ticket from the paypal widget i want to use condition to show the correct amount of guest list name fields for them to complete and upload journal ad image based on selection as well

That is possible.
First you need to integrate your Paypal Payment for your products such as Tickets.

Then you add the fields you want to collect such as "Amount of Guest" "Names" and "Upload"

After that you need to add a SHOW/HIDE condition that will trigger to show the fields if certain product is selected.

I have created a very simple example that will show Multiple Fields when the customer selected a Ticket. Please check out the link below.

You may also clone that form so that you can investigate and know how I did it.

There are also registration templates that are available for use.

Please let us know if you need further assistance, we will be glad to help you.
