Try this:

for ( var int = 1; int < 5; int++){
    obj['resposta'+int];
}

int isn't exactly a good choice of variable name, since it's easily confused with other languages where it's a keyword.

@Neil: Totally agree! Just gave an answer based on the given code. I didn't validate the code, neither did I show an example of what to do with the object, once it has been accessed, just showed the way to access it.
