for ( i = 1; i < Students.length; i += 1 ) {
document.write("<h2>Student: " + Students[i].Name + "</h2>") ;
for ( var prop in Students[i]) {
document.write([prop] + ": " + Students[i][prop] + "<br>" );
}
}

But you'll probably want to start the outer loop with "i = 0", since 0 is the index of the first item of an array. And you won't need any brackets around the word "prop" where it is used by itself.

for (var i=0; i<students.length; i++){
for (var prop in students[i]){
if (prop=="name"){
message+="<h2>Student: " +students[i][prop]+"</h2>";
}
else {message+="<br>"+prop+ ": "+ students[i][prop];
}
}
message+="<p></p>";
}
