How can i differentiate "variable","argument","parameter"&"attribute"?
Answers:
this is just my understanding/usage of these terms. so no gurantee:
all the term are variables because they are variable. A argument or a parameter are variables in a method signature/call. an attribute is a global variable aka field, property.
But everyones understanding might differ a bit. you shouldn't worry about the exact words as long as you know how to use such things.

A variable is mostly either a local varialbe (only used in a method) or a global variable (that can be used any where in the class).
An arguement is a verbal disagreement that you have with someone. 
An arguement or parameter is usually used when you are passing a value or values to a method. You generally use an arugement when making a method call and the actual method uses parameters.
An attirbute is a value that helps give a class definition. Example: A Person class could have the following attributes:
- eye colour
- hair colour
- height
- weight
