This is patent nonsense. Yahshua/Yeshua/Y'Shua is the familiar form or contraction of Yehoshua/Joshua (YHWH is our salvation). Yeshua, in Hebrew, literally means 'Salvation'. It means exactly the same thing in Aramiac, and the earliest Aramaic texts (contemporary with the earliest complete Greek, and predating your Talmudic sources) use 'Yeshua' for 'Jesus'. Yeshu/Yaesu/Yashu is simply a further familiar contraction (perhaps corruption) of Yeshua, which is not even evident until hundreds of years after the fact.
Messianic Hebrews use 'Yeshua'.
Aramaic Christians use 'Yeshua'.
At that time there were two main language groups in Israel, one spoke Hebrew, the Jews, and one spoke Greek, mainly the non-Jews.
In the Hebrew language this god has only be known as Yeshu, which is a foreign name, transliterated. It has no connection to any Hebrew name. The god has never been called anything but Yeshu. The same is probably true in India.
Aramaic? They spoke that in Syria to the north.
