Does the use of titles such as "you donkey" and "you idiot" among close friends who do not object to them and do not intend offense, conflict with the rulings of Sharia?

The believer should accustom his tongue to good speech and avoid obscene and vulgar language, due to the saying of the Prophet, peace and blessings be upon him: "The believer is not a slanderer, nor a curser, nor obscene, nor vulgar." "Al-Ta'an" refers to someone who frequently slanders people and their honor, "al-Fahish" is one who curses people with foul language, and "al-badhee'" is someone who has no shame or harms people with his tongue. The fact that a person does not get angry at these epithets does not negate that they are considered obscenity and vulgarity.
