أحسن الله اليكم in my mosque is a list of (order) who leads the prayer. if the iqamah is done and someone wants to lead the prayer but someone above him in the list enters. space is made for him to lead the prayer. is this correct and should the iqamah be done again? جزاكم الله خيرا

Ustadh AbdulAziz al-Haqqan

If u mean there are 2 Imams and 2 muthins etc then they r the Imam alratib yes and they should lead the prayer not others.
