Doing zikr collectively in chorus in the masjid

Q: In our musjid they recite a heart touching zikar after every fajr which goes like 'la Ila ilallah kareemus sataar,la ilah illah wahidul kahaar... they continue chanting different names/powers of Allah SWT in a definite order. I want to memorise it but can't find it on Google or YouTube because I don't know the name of this particular zikr.

Can you please tell me the name of this zikr so I can find this online.

Health insurance

Q: I have a question regarding to state life insurance company whether the health insurance of this company is halaal or haram.

My 2nd question is that my parents took a loan from a insurance company about 1 lac. Now they are going to do sadaqa/aqeeqah of a cow from this money. Is this is valid? 

Walking in front of a masbooq

Q: In a small Masjid, the Imam used a sutrah while leading the jamaat (it is a common practice in some places to do second or third jamaat if the main jamaat is missed). Is it permissible to pass in front of people who missed their rakaat with the Imam in these second/third jamaat are completing their prayers. Will they still be considered to be behind sutrah even if Imam has completed his own Prayer?
