There is a correct (or usual or idiomatic) ordering for adjectives, although it can sometimes be departed from to change the emphasis. There are various accounts of it (which differ slightly in the details).
Cambridge lists the ordering as follows:
1 opinion unusual, lovely, beautiful,
2 size big, small, tall,
3 physical quality thin, rough, untidy,
4 shape round, square, rectangular,
5 age young, old, youthful,
6 colour blue, red, pink,
7 origin Dutch, Japanese, Turkish,
8 material metal, wood, plastic,
9 type general-purpose, four-sided, U-shaped,
10 purpose cleaning, hammering, cooking
The British Council summarises the main rules as follows:
We usually put a general opinion in front of a specific opinion:
nice tasty soup,
a nasty uncomfortable armchair,
a lovely intelligent animal
We usually put an opinion adjective in front of a descriptive adjective:
a nice red dress,
a silly old man,
those horrible yellow curtains
Determiners. Determiners always come at the start. So the, that, his, some always come at the start.
You cannot have two determiners at the start. His some other texts is incorrect English. We would just say his other texts or some other texts (or we could say some of his other texts).
