No coffee is generally around pH 5. To be alkali it would need to be above pH 7.
Black coffee does not naturally contain any alkalis. It has a naturally acidic pH due to the organic acids present in coffee beans.
The solution become more and more alkaline and the pH increase.
The pH range for alkali substances is typically between 7.1 and 14. Alkalis have pH values greater than 7, indicating their basic nature.
When an alkali is added to an acid, the pH increases as the acid is neutralized by the base. This reaction forms water and a salt. The pH ultimately depends on the strength of the acid and the alkali.
any concerted alkali is weak alkali

No, it is an alkali according to the pH scale or pH indicator.
High. Acid have a pH of 1-6, neutral (eg water) has a pH of 7 and Alkali's have a pH of 8-14.
Some do. But all alkali have a pH value of more than 7.

No, the pH increases.
The pH range of an alkali solution is typically greater than 7, indicating that it is basic or alkaline. Alkali solutions have pH values above 7, with stronger alkalis having higher pH values.
Borax is an alkali, specifically a salt of boric acid. It has a basic pH value and can act as a buffer solution to help regulate pH levels in various applications.
Base = alkali
