assalamualikum is it correct to give multiple azaans at the same time for a single sallah
2 due to space constrains could jumma salaah be performed twice with one khutbah only
In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh
1.In principle, it is makrooh tahreemi to perform second jama`ah in a Shar`i Musjid that has an appointed Imam and a muazzin. 
It is permissible to call the azaan and iqamah separately for each salah in jamaat khana [musalla]. 
2.Khutbah is a condition for the jumma salah to be valid. Therefore, for each jumma salah two khutbas must be given. One khutbah for different jumma salahs is incorrect. 
And Allah Ta’āla Knows Best
