An Integer in an object that represent an int (Integer a = new Integer(3) would represent 3).
I'm not sure about Real.
A String is an object that represents a word. (String a = "dog")
Boolean
String

Hope this kind of helps
You can show your parents that you're responsible enough for a phone by volunteering to wash the dishes, or taking care of your siblings. Doing little stuff can prove that you're responsible. You should ask them, what they require you do to for a phone.
Good Luck!
