Alia is a good Quranic name, you can look at its meaning here: Alia
Zareen is a Farsi/Kurdish name meaning "golden", "made of gold". It is not an Islamic name but since the meaning is good it can be used by Muslims.
Since both Alia and Zareen have good meanings, you can use them together as a name inshAllah.
