        int pos = getIntent().getIntExtra("pos",0);      

        mWebView = (WebView)findViewById(R.id.webview);
        mWebView.setBackgroundColor(0);
        mWebView.setBackgroundResource(R.drawable.bg);
        mWebView.getSettings().setBuiltInZoomControls(true);
        switch (pos) {
        case 0:
            mWebView.loadUrl("file:///android_asset/History.html");
            break;
        case 1:
            mWebView.loadUrl("file:///android_asset/Mission And Objectives.html");
            break;

        case 2:
            /*Intent i = new Intent(getApplicationContext(), OurBranches.class);
            startActivity(i);
            break;*/
        default:
            mWebView.loadUrl("file:///android_asset/History.html");
            break;
        }


    }

The problem is that you override the first OnItemClickListener with the second, you have to do something like that:

public class OurSchool extends ListActivity{

String[] listItems={"History", "Our Vision", "Our Branches"};
boolean[] listImages= {true, true, true};


public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.our_school);
    setListAdapter(new ImageAdapter(this, R.layout.our_school, R.id.text1, R.id.image1, listItems, listImages ));

    this.getListView().setOnItemClickListener(new OnItemClickListener() {


        public void onItemClick(AdapterView<?> parent, View view, final int pos, long id) {

            Intent i;

            switch(pos)
            {
                default:
                case 0:
                    i = new Intent(getApplicationContext(), History.class);
                    break;
                case 1:
                    i = new Intent(getApplicationContext(), OurVision.class); // I assumed that this is the class name.
                    break;
                case 2:
                    i = new Intent(getApplicationContext(), OurBranches.class);
                    break;
            }

            // sending data to new activity
            i.putExtra("pos", pos);
            startActivity(i);
        }
    });
}
}

So you just need to put one OnItemClickListener and implement inside a switch to create the different Intents for every Activity:

    this.getListView().setOnItemClickListener(new OnItemClickListener() {


        public void onItemClick(AdapterView<?> parent, View view, final int pos, long id) {

            Intent i;

            switch(pos)
            {
                default:
                case 0:
                    i = new Intent(getApplicationContext(), History.class);
                    break;
                case 1:
                    i = new Intent(getApplicationContext(), OurVision.class); // I assumed that this is the class name.
                    break;
                case 2:
                    i = new Intent(getApplicationContext(), OurBranches.class);
                    break;
            }

            // sending data to new activity
            i.putExtra("pos", pos);
            startActivity(i);
        }
    });
