Declare data in the custom program based on data type (TY_MARA in this case) declared in the global class (Z_TEST). 
In this case data type(TY_MARA) is declared as public. So we have created an object of global class and then use the object to refer the data type in our data declaration.
Note:
This solution only works if data type is declared in the global class as public.

Is there any way to access the global types inside our exit?.
Eg : In Program MV45AZZ, global types has been declared as GY_XXX.
I need to reuse this global types inside my exit.
data : lt_table type table of ( 'SAPMV45A'(gy_xxx) ).
is there any way to reuse the types from top include?

Yes we can use like below. Constant should be public.
Class=>constant
