How does having other mental conditions affect the symptoms one may experience from schizoaffective disorder?

Which?: Schizoaffective already has a wide range of expression. Dual DXs may make things more difficult to manage - but try not to pay too much note to the names. Let your treatment team help and focus on how you handle your daily life. That's what you need to do in any case. It's not too different than having a head cold and also a lower back issue - you'd feel worse and need to be extra careful. Best!
