about azaan and iqama, and other...

Salam alaikum

Bismillah ArRahman ArRahim

Suallu al al Habib sallalahu alaihiwassalam

I know that before praying we should do azan and iqama.

But for exemple in this situation :

It's asr time, and I am performing 4 sunna , 4 fardh and 3 fardh qaza of maghrib.

1) Should I make azan like in masjid in loud voice that all house can hear me ? Cause when I am praying with other they make only iqama without azan.

2) if I have a clock in my house that give azan, should i give azan also ?

3) should i give azan and tha iqama then start with sunna ? Or should i give azan than performing sunna, than iqama and then fardh ? And in this case, should I make-up iqama before qaza of maghrib ?

4) Can I read qaza maghrib in loud voice if i am in asr time?

5) If a catch jamaat in the last rakat after ruku but before the salam of imam, will i get the sawab of jamat?

6) I heard that if our wuzu in salat is broken and we continue to pray it can lead to kufr ?

7) when we say to not read durud during juma khutba , it's during the khutba in urdu ? or the small khutba in arabic just before juma salat ?

Jazaka Allah
