Rise, хорошо, исправляюсь!
k_DizeL, например, так:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script>
$(function() {
    var counter={},
        oldVal={},
        oldName;
	var limit = {t1: 2, t2: 2, t3: 3};
	$("[type='radio']").on("click", function() {
		var name = this.name;
        if (oldVal[name] != this.id){
			if (counter[name] != undefined){
				counter[name]+=1;
			} else{
				counter[name] = 1;
			}
			if (counter[name]>limit[name]){
				$("[name='" + name + "']").prop('disabled', true);
			}
			oldVal[name] = this.id;
			if (oldName && oldName != name){
				$("[name='" + oldName + "']").prop('disabled', true);
			}
			oldName = name;
        }
		
	});
});
</script>
