How do you say 8 in the morning Kikuyu language?

Ndugu ino ya mũthenya (pronounced: N-doo-goo ee-no ya moo-the-nya)

This literally translates to "the eighth hour of the day".

You can also say:

* Indi ya mũthenya (pronounced: In-dee ya moo-the-nya), which means "eight o'clock in the morning."

Keep in mind that Kikuyu language does not use a 12-hour clock system.
