Multiple Raycasts

Hello,

I'm trying to get 5 raycast systems to work but I'm having difficultly trying to offset them.

What I'm trying to do is to have a raycast come from my Input.mousePosition, but also have 4 other raycasts around that, that are slightly offset. But I suck when it comes to vectors.

So basically, this is how I want my set up:

 var hit : RaycastHit;
 var ray = Camera.main.ScreenPointToRay (Input.mousePosition);
 var layerMask = 1 << 14;
 
 Physics.Raycast (ray, hit, 200, layerMask); // center line
 
 Physics.Raycast (ray, hit.(z + 2) (x -2), 200, layerMask); // upper left
 
 Physics.Raycast (ray, hit.(z + 2) (x +2), 200, layerMask); // upper right
 
 Physics.Raycast (ray, hit.(z - 2) (x -2), 200, layerMask); // lower left
 
 Physics.Raycast (ray, hit.(z - 2) (x +2), 200, layerMask); // lower right

This obversely isn't going to work, but thats what I am trying to achieve. So each raycast that is being shot from the Input.mousePosition is to be offset by +2/-2. I also have a feeling that it has nothing to do with the 'hit', but is to do with the ray that I need to be adjusting?

I would appreciate any help with this.

------ UPDATE ------

Okay, so I'm making some progress. I have 5 raycasts that are shot with an offset from the camera, but towards the other end of the shot, they are angling towards each other. Here is a screen shot to help explain:

Here is my current code:

 var hit : RaycastHit;
     var ray = Camera.main.ScreenPointToRay (Input.mousePosition);
     var layerMask = 1 << 14;
     var hitPoint : RaycastHit;
     
     if(debugClick){//chooseLocation){
         layerMask = ~layerMask;
         // center line
         Physics.Raycast (ray, hit, 200, layerMask);
         Debug.DrawLine (ray.origin, hit.point);
         
         // line 1
         var offset = Vector3(ray.origin.x + 2, ray.origin.y, ray.origin.z);
         var direction = transform.position;
         Physics.Raycast (offset, direction, hit, 200);
         Debug.DrawLine (offset, hit.point, Color.green);
         
         // line 2
         var offset2 = Vector3(ray.origin.x - 2, ray.origin.y, ray.origin.z);
         var direction2 = transform.position;
         Physics.Raycast (offset2, direction2, hit, 200);
         Debug.DrawLine (offset2, hit.point, Color.red);
         
         // line 3
         var offset3 = Vector3(ray.origin.x, ray.origin.y, ray.origin.z + 2);
         var direction3 = transform.position;
         Physics.Raycast (offset3, direction3, hit, 200);
         Debug.DrawLine (offset3, hit.point, Color.blue);
         
         // line 4
         var offset4 = Vector3(ray.origin.x, ray.origin.y, ray.origin.z - 2);
         var direction4 = transform.position;
         Physics.Raycast (offset4, direction4, hit, 200);
         Debug.DrawLine (offset4, hit.point, Color.yellow);123
