Can regular pumpkins be used for pies?

No, regular pumpkins are not suitable for making pies. The most frequently used type of pumpkin for pie-making is called the "sugar pumpkin" or "pie pumpkin". Compared to regular pumpkins, sugar pumpkins are smaller, sweeter, and contain a denser, drier, and smoother flesh, which creates a smoother and richer pumpkin purée texture suitable for pies.
