What/Who Else?

Alatulya maquetienyasse. Which word can be used for "else" in the contexts of "who else" and "what else"? Can exa and hyana also be used in this context? If so: Is the phrase/sentence "Man hyana?" right? It just sounds pretty wrong to use the word for "other" in this context, but what is the alternative?

Many real-life languages use other. But I would use man hye? what other person?, man hya? what other thing?

That sounds logical. Thanks.
