Is there a fee for each individual or no

but really just support your state parks and buy a year pass! it's relatively near the cost of 2 or 3 day passes. edit: if you're a Michigan license plate, you can buy the year park pass and have it on your plate if you don't like sticky things in the window

The fee is per vehicle

No it's not individual you can buy one day pass or seasonal pass for all state parks

I never been here and me and my friends were trying to meet up here and find out the prices

It's per car.

For car
