1) Ch. 45, v. 17: "Zose asu taanu es b'irchem" Thus shall you do load your animals The words "zose asu" seems totally superfluous. "Do this" is usually a response to some reluctance on the other party's position or a counter offer to his plan. Here we see no reluctance and no previously offered alternative plan.
2) Ch. 46, v. 17: "Ulchu bo'u" And go come The word "bo'u" is problematic.
3) Ch. 46, v. 28: "V'es Yehudoh sholach l'fonov Goshnoh" And he sent Yehudoh ahead of him to Goshen Rashi says that Yehudoh was sent to establish a house of Torah study. If so, why not send either Shimon or Levi, who were destined to be Torah teachers?
4) Ch. 47, v. 8: "Kamoh y'mei shnei cha'yecho" How old are you What prompted this unusual question?
5) Ch. 47, v. 18: "Bashonoh hasheinis" In the second year Rashi says that this is the second year of the famine. Accordingly, the time line here is before Yaakov's descent to Egypt with his family and his meeting with Paroh, as is explained by Rashi in verse 13. In verse 18 Rashi says that once Yaakov descended to Egypt the famine came to an abrupt end. He bolsters this with the words of the Tosefta on the gemara Sotoh.
The obvious question that comes to mind is: Wouldn't the trust in Yoseif's interpretation of the dreams, that there would be 7 years of famine following the 7 years of abundance, be compromised?
