As Salam Aleikhum can I call Isha Rashool Allah or YA Rashool Allah as Muhammad Rashool Allah.because Isha is also my prophet as Muhammed is my prophet can I give same reference to Isha.
Jesus was a Prophet and a Messenger just like Moses and Muhammad, so yes you can call him رسول الله and this is proven in the Quran:
المسيح عيسى ابن مريم رسول الله وكلمته القاها الى مريم وروح منه
Al-Masihu `Isa Abnu Maryama Rasulu Allahi Wa Kalimatuhu 'Alqaha 'Ila Maryama Wa Ruhun Minhu
The Messiah, Jesus, the son of Mary, was a messenger of Allah and His word which He directed to Mary and a soul from Him.
واذ قال عيسى ابن مريم يا بني اسراييل اني رسول الله اليكم مصدقا لما بين يدي من التوراة ومبشرا برسول ياتي من بعدي اسمه احمد
Wa Idh Qala Isa Abnu Maryama Ya Bani Isra'ila Inni Rasulu Allahi 'Ilaykum Musaddiqaan Lima Bayna Yadayya Mina At-Tawraati Wa Mubashiraan Birasulin Ya'ti Min Ba`di Asmuhu 'Ahmad
And [mention] when Jesus, the son of Mary, said, "O children of Israel, indeed I am the messenger of Allah to you confirming what came before me of the Torah and bringing good tidings of a messenger to come after me, whose name is Ahmad."
I'm not sure if you'd say "ya rasul-allah" unless you were talking to him.
No. Reason is we were send a rasuul (Mohammad ibn Abdullah ibn Abdulmutalib ibn Hashim ) SAW. He is representative for Isa ibn Maryama AS. Isa was not sent for all creation. Therefore his message/mission was not completed. Until new prophet to complete the cycle and Isa to return to only confirm that he is Muslim. So Rasuul lulaah is only applicable to the latest 1 which is the 1 you follow.
