Get the ticket holders into a list
One row per ticket is the simplest approach: five tickets means five rows, and the draw takes care of itself. If your records are one row per person with a quantity column, use that column as the weight during import instead.
Draw the prizes in order
Set the number of prizes and draw them in sequence — first prize, then second, and so on. Each winner leaves the wheel, so one ticket cannot take two prizes.
Announce it properly
Copy result gives you the title, the winners in order and the entry count as plain text. If people are going to ask, record the draw instead: the video carries the entrant count, the time and an Entry List ID for the exact ticket list.
Raffles are regulated differently in different places, and some are only legal for registered charities or with a licence. Spinnza picks names; it does not make a raffle lawful.
