Qasar Salaah and Full Salaah

Musaafir staying in a place for 15 days and travelling safr distance in between his stay

Q: I've travelled from Mumbai to Jaipur (distance 1150 km) on 30th Aug 2019 on an official visit and my stay will be till 14th Sep (total of 15-16 days). Insha-Allah on 2nd Sep I'll be going to Ajmer for 1 day on a personal visit (distance 135 km) and shall come back on the same day to the same hotel. After coming back I'll stay upto 14th Sep for offical work.

After arrival in Jaipur, should I offer qasar namaaz as per hanafi school of belief?

Will a person be regarded as a musaafir if he is studying 76km from his home town

Q: I am from Roshnee, studying in Azaadville (distance between Roshnee and Azaadville is 76 Km). My wife is from Rustenburg which is +/-100 km to Azaadville.

So we staying together here in Azaadville, but I do not intend ever settling down here because I have to basically just finish my studies.

Ps. We usually don't stay here for more than 15 days. So can the following intentions be permissible: 

My niyyah: My darul watan is still Roshnee, I make niyyah for safr when I leave Roshnee intending to continue my journey more than safr distance, and stay in Azaadville for less than 15 days (by our flat).

My wife's niyyah: She keeps Rustenburg as her darul watan as she hasn't established herself anywhere else yet, not Roshnee nor Azaadville. Azaadville is just a darus safr as she will not stay for more than 15 days like myself. She reads qasr when in Roshnee.

So do I read qasr in Rustenburg? Are these intentions correct or should we change our niyyah to base ourselves in Azaadville and work accordingly or what is Mufti Saheb's opinion?

Travelling safr distance from watn-e-iqaamat

Q: I decided to travel to Dammam for 17 days. In between I went to some other town for 3 days which is approximately 200kms from Dammam.

My question is, after I came back to Dammam, do I need to pray qasar or full namaz? Initially it was more than 15 days stay so I was praying full namaz but after moving out of town and coming back and less than 15 days of stay left, so will it be qasr or not?
