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];
	}
}

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;
}
