Absolutely people in systems change their name just like anybody else. I have changed my personal name in the earth world (not the legal name, but my name) three times, and I have two names at present -- Bluejay for the earthworld, Kairu for back home. It's no different for a person in a system to change their name than for a singlet in the earth world to do a legal or deed poll name change. Same with everything -- people in multiple systems are born, die, marry each other, have kids (ask the qilora about this), do various types of work...
This idea of one name and one name only is a western, European convention. In some native American traditional cultures (especially High Plains people), you never go through your whole life with the same name. Seven or eight names is not at all unusual.
And just like you'd expect, U.S. government officials couldn't stand the idea that Indians did this. One report said something like it was "meaningless and primitive" and showed that we lacked a sense of individual identity. What they really meant was that they couldn't keep track of us if we did that.
