After Abraham, Isaac, and Jacob, some of the Torah-leaders were: Levi, Kehath, Amram, Moses (see Exodus ch.6), Joshua and Elazar, Pinchas, Othniel, Ehud, Boaz (of the Book of Judges), Eli, Samuel, David, and the prophets throughout the era of the kings. Also, after the time of Jacob, as soon as the Israelites were numerous enough, the Sanhedrin (Torah-council of Elders) was instituted (Talmud, Yoma 28b) and functioned for millenia.
After the era of the Prophets, some of the leaders were: Ezra, Shimon haTzadik, Antignos, Yosi ben Yoezer, Joshua ben Perachiah, Shimon ben Shetach, Shemayah, Hillel (Avot ch.1), Yochanan ben Zakkai, Rabbi Joshua, Rabbi Akiva, Rabbi Meir, Rabbi Judah. There are, of course, many thousands more. The above names cover the first two thousand years, in order.
It depends on how the term is meant. "Torah Jews" can mean more than one thing. If the definition is: Those who live the laws of the Torah (which is the way the phrase "Torah Jews" is usually used), then it is understandably common to reserve that description for observant Jews. It is indeed customary today to call observant Jews "Torah Jews"; so the answer to the question is Yes. The word "Orthodox" is seen by many Torah Jews to be an exonym, i.e. a term applied to them by non-Orthodox, whereas they prefer the term "Torah Jews". If the definition is: Who is Jewish according to the Torah, then Torah Jews would include non-observant Jews, because they don't cease being Jewish. All Jews, regardless of levels of observance are "Torah Jews" since their Jewishness is derived from the Torah's mandates.
