فَإِنْ فَاتَتْهُ صَلَوَاتٌ: أَذَّنَ لِلْأُولَى وَأَقَامَ
Translation: If he has missed multiple prayers, he gives the adhan and iqamah for the first one.
When several missed prayers are made up consecutively, both calls are given for the first prayer. A facilitation applies to the remaining prayers.
This is the sequence described for several make-up prayers in one continuous setting, not an exhaustive rule for every separate setting.
