Best way to create multiple characters with the same stats

Lets say I want 10 characters but they are all having something the same but different.
I want to for example have one called Dave and one called David, if I call for david’s health I want 100/100 for example and Daves health should be 80/80, but they both have health, they also might have clothes on but one of them has a red shirt and the other a blue one but they both have a shirt and I want to be able to call this from each and everyone of them what would be a good solution for this?

You should check the tutorials on scripting, this one about classes might be perfect for you.
