Can more than one person track the same AirTag?

Only if you both shared the same Apple ID ... and that would definitely NOT be recommended. As the others have already mentioned, the AirTag can only be associated with a single ID.

I assume you mean AirTag, not airbag. And no, I'm afraid not. AirTags can only be paired to one account.

Apple does not make or sell airbags
