Get any specifically tagged GameObject that has a specific value?

Hello, what I am trying to accomplish is to somehow get an object that has specific variable integers and a specific tag to somehow get components from the specific object.

Here's some code that might explain what I am trying to do:

     public  int SelectPointVarX0;
     public  int SelectPointVarX2;
     public  int SelectPointVarY1;
     public  int SelectPointVarY3;
 
 
     public GameObject SelectPointObjectX0;
     public GameObject SelectPointObjectX2;
     public GameObject SelectPointObjectY1;
     public GameObject SelectPointObjectY3;
 
 
     void ActivateTile(){
 
 
 
         GameObject[] objs;
 
         if (ActiveObjectSet == true) {
             objs = GameObject.FindGameObjectsWithTag ("Tile");
 
             foreach (GameObject GridFloor in objs) {
 
 
                     SelectPointObjectY3 = GridFloor.GetComponent<GridLifeSupport> () // and has 
                     Ynumber == SelectPointVarY3 to be a specific object;
 
                     //like if SelectPointVarY3 = 2 , then the SelectPointObjectY3 would be a specific object and if SelectPointVarY3 was another value, then would be a different object
