A Cipher of Margret of Austria?

A cipher used in the correspondence of Margaret of Austria, Governor of the Habsburg Netherlands in 1507-1515, 1519-1530, is preserved in Archives départementales du Nord (Un jour, une œuvre : un code secret aux Archives départementales!, 1 June 2022).
I believe the third image posted, if any, belongs to Margaret of Austria. It is a short list of symbols for names. Historians will be able to date it from entries such as
Soliciteur
de Zorn
de Bure
de fiennes
de Sempy
de Silstein
Brossart de fauquemont
Paule de Lichtein

The first image shows a simple substitution cipher alphabet which assigns numbers to the letters A-Z plus J at the end, with homophones for A, E, I, O, S, V. The syllable section assigns number to some (fa is enciphered as 35, fe is 36, etc.), but substitutes syllables for others (da is enciphered as fa, de is fe, etc.). Such mixed ciphers are known from Spanish ciphers in the 17th century (e.g., Cp.59, Cp.64, for which see my article).

The second image is part of a nomenclature, assigning numbers 266 to 614 to letters, syllables, words, names, and some functions. The entry of Queen Christina clearly shows it is no earlier than 1632. The following shows some entries of interest, from which I guess this is from 1682-1689.
