Rashi #1 (citing Menachem ben Seuk) and Rashbam: It means still a long distance away. ¹

Rashi #2 (citing the Midrash): It refers to the time of year - in the spring, when the land is full of holes like a Kevarah (sieve) ² , and it is pleasant to travel (Sifsei Chachamim).

Ramban (citing the Redak): The distance that one travels between daybreak and breakfast.

Rashi #3: It is a measure of land, about a Parsah (four Mil).

Rashi (48:7, citing R. Moshe ha'Darshan): It is a Mil (2000 Amos), the equivalent of Techum Shabbos.

Ramban: It is a small measure of land, less than a Mil. When I came to Eretz Yisrael, I found that Kever Rachel is less than a Mil from Beis Lechem.

Ramban and Targum Yonasan: The Pasuk in Yirmiyah is a Mashal, as if to say (not that Rachel was buried in Ramah, but) that - so loud were Rachel's cries for her children that they could be heard in Ramah ¹ (in the portion of her son Binyamin). ²

Malbim: Yakov married two sisters. This was permitted before Matan Torah, and Hashem told him to do so, to father the Shevatim. After Hashem blessed him to be under Divine Hashgachah, this was like after Matan Torah, and it was improper to be married to two sisters, especially after the last Shevet was born. For the same reason, she was not buried in Me'aras ha'Machpelah.

Ha'Emek Davar: Midas ha'Din struck Yakov. ¹

Ramban (Vayikra 18:25): This was Hashgachah. She merited to die in Eretz Yisrael, and Yakov merited that he not transgress being married to two sisters in Eretz Yisrael. The Avos kept all the Mitzvos in Eretz Yisrael. (Hagahah in the Rosh, verse 19).
