I've a character that walks from waypoint 0 to 1 from 1 to 2 from 2 to 3. the character reaches from 0 to 1 it waits 1.5 seconds, and then when it gets to the 2nd waypoint it doesn't wait 1.5 seconds, and so on..

var waypoint : Transform[];
var speed : float = 3;
var currentWaypoint : int;
var loop = true;
var test;

function Update () {
    animation.wrapMode = WrapMode.Loop;
    var controller : CharacterController = GetComponent(CharacterController);
    if(currentWaypoint < waypoint.length){
    var target : Vector3 = waypoint[currentWaypoint].position;
    var moveDirection : Vector3 = target - transform.position;

    if(moveDirection.magnitude <= 1.5){
        print("magniute");
        animation.CrossFade("idle");
        speed = 0;
        WaitThreeSeconds();
        if(test){
        test = false;
        currentWaypoint++;
        }
        if(currentWaypoint == 3){ currentWaypoint -= 3; }
    }
    else{
        animation.CrossFade("walk");
        speed = Random.Range(0.8,2.01);
        RotateTowards();
    }
}
        //print(moveDirection.magnitude);
        controller.SimpleMove(moveDirection.normalized * speed);
}

function RotateTowards () {
var target : Vector3 = waypoint[currentWaypoint].position;
var moveDirection : Vector3 = target - transform.position;
    while(Vector3.Distance(target, transform.position) >= 1.5){
    transform.rotation = Quaternion.Slerp (transform.rotation, Quaternion.LookRotation(moveDirection), 0.5* Time.deltaTime);
    transform.eulerAngles = new Vector3(0, transform.eulerAngles.y, 0);
    yield;
    }
}

function WaitThreeSeconds(){
yield WaitForSeconds(1.5);
test = true;
}

Try put WaitThreeSeconds(); down by a line into the if(test) block

That should sort it

Solution :

var waypoint : Transform[];
var speed : float = 3;
var currentWaypoint : int;
var loop = true;
var test;

function Update () {
    animation.wrapMode = WrapMode.Loop;
    var controller : CharacterController = GetComponent(CharacterController);
    if(currentWaypoint < waypoint.length){
    var target : Vector3 = waypoint[currentWaypoint].position;
    var moveDirection : Vector3 = target - transform.position;

    if(moveDirection.magnitude <= 1.5){
        test = true;
        print("magniute");
        animation.CrossFade("idle");
        speed = 0;
        if(test){
        WaitThreeSeconds();
        currentWaypoint++;
        }
        if(currentWaypoint == 3){ currentWaypoint -= 3; }
    }
    else{
        if(!test){
        animation.CrossFade("walk");
        speed = Random.Range(0.8,2.01);
        RotateTowards();
        }
    }
}
        //print(moveDirection.magnitude);
        controller.SimpleMove(moveDirection.normalized * speed);
}

function RotateTowards () {
var target : Vector3 = waypoint[currentWaypoint].position;
var moveDirection : Vector3 = target - transform.position;
    while(Vector3.Distance(target, transform.position) >= 1.5){
    transform.rotation = Quaternion.Slerp (transform.rotation, Quaternion.LookRotation(moveDirection), 0.5* Time.deltaTime);
    transform.eulerAngles = new Vector3(0, transform.eulerAngles.y, 0);
    yield;
    }
}

function WaitThreeSeconds(){
yield WaitForSeconds(1.5);
test = false;
}
