Dua #1.
رَبَّنَا آمَنَّا فَاكْتُبْنَا مَعَ الشَّاهِدِينَ
المائدة :83
The word “Amanna” does not refer to the Ahlul-Kitab’s past Iman but it refers to their bringing Iman of the present and being included amongst the group of believers. The word Rabbana clarifies that they are bringing the true Iman and not the superficial Iman like the hypocrites. By the word “Ash-shahidin” the ummah of Nabi (Sallallahu alaihi wasallam) is meant, those who will give testimony regarding the conveyance of the message of Nabi r.
Rabbana aamana faktubna ma' ash-shahideen
Our Lord! We believe; write us down among the witnesses. - 5:83

When Esa (A) saw that their objective was valid he made this dua
