The believe magnum wings are load rated between 350 to 400 lbs. I wouldn’t put more then two people on a wing regardless of weight. (Also don’t want to ask the women their weight.

That would be more hazardous then anything else.)
I would keep it down to 4 people max. If the win is reasonable you can probably solo with three passengers easily. If one of the passengers can handle the jib sheets when you tack/jibe, that would help. I’d just set the jib and forget it.
If you plan to fly a hull I’d include a briefing to the passengers about what to do in case you capsize. (With 4 people flying a hull would be difficult except in good winds.)
Pay your insurance premium and have fun.
