Are "Sheikh Khalil," "Imam Al-Nafrawi," "Al-Taj," and "Al-Iklil" considered well-known and reliable figures?

The scholars mentioned, and the book "At-Taj wa Al-Iklil" by Al-Mawwaq, are among the relied-upon commentaries on Mukhtasar Khalil. As for An-Nafrawi—whose name is Ahmad ibn Ghunaim—he was one of the Azhari scholars of the Maliki school in the twelfth century Hijri, and his most famous book is "Al-Fawakih Ad-Dawani."
