can you give the clearest possible adjectives in these Spanish sentences?

Question

Example:
Los tíos de José.
Los tíos de él.



1. los hermanos de Juana
2. la amiga de José
3. mi tío y tu tía
4. la abuela de Pedro y el abuelo de Andrés

Answer 1

In the example you substituted a pronoun (él) for a noun (José). Are you sure you want adjectives? Adjectives modify nouns, they don't replace them.
An adjective would be, for example, "feos" (ugly) as in, "Los tíos feos de José." "Feos" modifies "tíos."
