What would you do if you and other 9 people in an aiplane crash landed on a non identified Island, which makes it hard to get rescued. Right?

The pilot and other died, the only survivors are 9 people and you: 10 people.
2 kids with with their father
A 6 months pregnant woman
An old couple who are almost 80 years old
2 single women and 2 sigle men ( 19-27 years old)

What will you do first? Who should be in charge? What will you eat or drink? what if you get hurt? How will you live? What will you if anyone die?

After you all have somehow built a funktional society island, what would you do if a new group of 20 people arrive at the Island with a boat because their airplan Crashed too. And they dont speak the same language like youn

There is no connection, so you can't call or use a radio to call SOS for help so you all gave up to screem for help and you start to do something to survive. None of you have food, so you have to hunt, fish, grow seeds/plants and none of you have any materials to build a house or to make fire with. It will be living like a cave man.

The plane sank in the ocean, so you have no supplies and no medical supplies. The only things you have is what you are wearing.
