I have two objects, lets say user_1 and user_2 that do not belong to the same class, I want to know if it is possible to store them in the same array.

On what context of data you are talking about?

Actually I have defined one class called "User" after that I realized that I will need to define 2 types of users using two classes, lets say UserType1 and UserType2.
The problem is that my code was working using an array of users of the old class "User" only. When I defined two seperate classes I wasn't able to store the users of different classes in the same array and all my code was about this array.

Yes, if that array is a cell array. Cell arrays can store any mixture of types,
array={user_1, user_2}

if I have 2 users (from different classes) in the same cell array and I want to get the values of a common property between users, how can I get this property (for example the users id) I guess cell array doesn't support the dot indexing.

Okay I see. I've tried the suggestion of Steven Lord in the comment below and it's working using a simple array. The class of the array is the super class 'User' but it contains objects from different classes that inherit from the super class. Thanks for your help!

If those objects are in the same class hierarchy, you could make the hierarchy heterogeneous.
