Hajj & Umrah

Couple having relations before tawaaf-e-ziyaarah

Q: There is a couple that recently came from hajj. They did all things correct but they have 1 doubt. 

After coming from Muzdalifah, doing 1st rami, and cutting of hairs/halaq, they opened their ihram and after that they thought they are open from ihram and out of ignorance and oversight they did sexual relations just before tawaf e ziarat. 

Tawaf e ziarat was done after gusal and proper clean cloths? Would they be required to give damm? If yes, will it be for both or just 1?

Haaji pelting on the 12th morning before zawaal

Q: This year while performing hajj, the Saudi Government directed the pilgrims to start performing the 12th dhul hijja rami after Fajr due to excessive heat and overcrowding to avoid any untoward situation. So, we performed the rami before zawal on 12th dhul hijja. 

Is my hajj acceptable or do I need to perform anything to compensate for performing rami before zawal? Are there any rulings or views of scholars on performing rami before zawal?
