I stay in gulf country where our mosques are hardly few and the place where I work is far from our mosque. Can I pray my zohar and Asr at any other mosque with my hands folded (in taqiyah) and will it be counted as a valid prayer and performed at avale waqt or I should have to repeat my prayers once I am back home as per the teachings of fiqhe Jaferiya.

Yes, you can, but there is no need to fold the hands, as not all other sects fold their hands.
