My code is written in C and I am using your HAL library I need to set/Reset 6 GPIO pins on the same port now I iam doing it by calling 6 times to HAL_GPIO_WritePin which take too much time how can I do it in one cpmmand since all pins are of the same port.

Look at using GPIOx->BSRR more directly.

Or more generally, a study of the Reference Manual (GPIO section) won't hurt.
