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 the same Demat account or same PAN Number, all your applications will be rejected.

If you would like to place the order for multiple applications, then it is recommended that you apply using each of your family members' name. But again all eligible family members should have a demat account and a PAN number.
