The max is actually 15 for on trail hikes, 8 for off trail.
You're getting a late start and it's a holiday weekend. You need to go to nps.gov/yose and visit the wilderness page, and look at the trailheads report and see which still have room on them. Look at the quotas for the trailheads, and assess the likelihood that you'll get your whole group on one of them.
Trailheads you will most likely be able to get will be Ostrander (Lost Bear), Chilnualna (near Wawona, uphill steadily for four miles), Alder Creek, Bridalveil Creek, Mono Meadow....
Get a map and look at mileages, and understand that you will need to be flexible. A large group plus last minute planning is stacked against you.
Don't forget to leave room in about half the packs for the bear canisters you will need to rent. No canister, no permit. Save a bear, avoid a fee and being thrown out of the park, use the canisters.
