A Tau name has several parts.
Part 1 is Caste and Rank. Your caste is effectively Gue'vesa (Human Helpers) but the Tau use their own Caste system: Fire caste (Shas), Air caste (Kor), Water caste (Por), Earth caste (Fio) and the Ethereal caste (Aun). Each caste has five ranks, 'La, 'Ui, 'Vre, 'El and 'O.
Everyone is a Gue'vesa'La except Sergeants who are Gue'Vesa'Ui, Fire Warriors who are Shas'La, and Kroot Carnivores who are Pech'vesa'La
Part 2 is your Sept. Your Sept is Dalyth.
Part 3 is a given personal name that was probably given to you when you completed your training. These are just words a link to a list of tau words is below but you can just use English if you can't find something you like.

Put it all together your full name might be.
Gue'vesa'La Dalyth Ukos (Presumably there is a long story why you were awarded the name Spoon)
Usage
Saying Gue'vesa'La Dalyth Ukos is a mouth full and is generally only going to be used on very formal occasions (government forms, couts martial, etc.)
Simply using the given name is very familiar, like what your family might call you.
Rank and Given name is reasonably the most common form of address La'Ukos (equivalent to Private Ryan for example)
Simply Caste and Rank is slightly more formal for an unknown officer or in a combat situation. "Yes, Sash'Ui!" would be equivalent to "Yes, Sergeant!" or even "Yes, Sir".
