how to priority of interrupts

I'm not quite sure I understand what you mean. If you have two interrupts that both will cause GPIOTE_IRQHandler to run, one will not interrupt the other, and as far as I've seen, GPIOTE_IRQHandler will be called until all events are cleared.

You can not explicitly set the priority of individual events handled in the same IRQ handler. If your interrupt handler checks all events, it may clear all events on the first run, and if so, the sequence will be determined by the sequence in which you check the events in your IRQ handler.

If I don't understand you correctly, could you please edit your question and supply a code example showing the problem you're having?

You can set the priority for any interrupt using NVIC_SetPriority()/sd_nvic_SetPriority().
