“No”, one person cannot apply multiple times through multiple applications for an IPO. It's a rule and if you apply in an IPO through multiple applications with the same name or same demat account or same PAN Number, all of your applications will be rejected.
If you would like to place an order for multiple applications, it works if you apply one each of your family member's name. But again all eligible family members should have a demat account and a PAN number.
If your family member does not have a demat account please click here to open.
