You never set SecondndMaterial3 to true. Change the second if conditional to this:

 else if(SecondndMaterial)
 {
     renderer.material = logo;
     FirstMaterial = false;
     SecondndMaterial = false;
    SecondndMaterial3 = true;
 }

I'd create a simple public array of materials, set the size and materials in the inspector. Then you'd want to use an int for the index, then simply cycle through on each click.

 using UnityEngine;
 using System.Collections;
 
 public class Example : MonoBehaviour 
 {
     public Material[] materials;
     int index = 0;
     
     void Start()
     {
         renderer.material = materials[index];    
     }
     
     void OnMouseDown()
     {
         index++;
         if(index >= materials.Length)
             index = 0;
         renderer.material = materials[index];
     }
 }

Thank you! This worked for me, but I had to make sure a collider was on the affected objects. And for the newer Unity versions ($$anonymous$$e 2021), the wording is: GetComponent(less-than)Renderer(greater-than).material = materials[index];

*this forum page doesn't allow those less/greater-than symbols, its weird
