Answer 1

You can share the same layout file and the set the attributes for views in the onCreate(..) method of each activity.

If you want a different URL to open for each image button you could set it at runtime as follows

public void onCreate(Bundle b) {

    Button button =(Button)findViewById(R.id.button);
    button.setOnClickListener(new OnClickListener(){
        public void onClick(View v) {
            //different action for each activity
        }
    });
}

Answer 2

Yes you can! I had multiple activities inflate the same layout but they save different shared preferences.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.same_layout);

    TextView urlDesc = (TextView)findViewById(R.id.descriptionviewer);
    urlDesc.setText("url_1"); //now in other activities-- urlDesc.setText("url_2");


    ImageButton aButton = (ImageButton)findViewById(R.id.videolink);
    aButton.setOnClickListener(aButtonListener);
}

private OnClickListener aButtonListener = new OnClickListener() {
    public void onClick(View v) {
        // go open url_1 here. In other activities, open url_x, url_y, url_z
        finish();
    }
};

Same code just swapping the text you want to set for the TextView and url to open in OnClickListener(). No more to change.
