@Override
public boolean onOptionsItemSelected(@NonNull MenuItem item) {
    int _id = item.getItemId();

    // Select tablayout using option Menu
    TabLayout tabLayout = (TabLayout) findViewById(R.id.tablayout);
    TabLayout.Tab _tab;

  switch (_id)
  {
      case R.id.mnutabindx0Frag2: //show first tab  with second fragment 
          //Set the Tab index to show
           _tab = tabLayout.getTabAt(index:0);
          _tab.select();


          //Close the fragment of the target tab
          getSupportFragmentManager().beginTransaction().remove(new Frag_First()).commit();
          // set the Fragment to show
         getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
                 new Frag__Second()).commit();

          break;
      case

You do not need to call

//Close the fragment of the target tab

      getSupportFragmentManager().beginTransaction().remove(new Frag_First()).commit();

Since, replace call removes other added fragments of a same containerViewId

Ok I got it, First I preapare two different Fragment Container, ViewPager and FrameLayout. then I used FameLayout to handle the replacement Fragment, after that I set the visibility depend on the condition I made.

    //Fragment Container Visibility method
private void _setvisibility_FragContainers(FrameLayout fl, ViewPager vp,boolean flflag)
    {
        if(vp.getVisibility() == View.INVISIBLE & flflag ==false )
        {
           vp.setVisibility(View.VISIBLE);
           fl.setVisibility(View.INVISIBLE);
        }
        else if(fl.getVisibility() == View.INVISIBLE & flflag == true) {
          vp.setVisibility(View.INVISIBLE);
          fl.setVisibility(View.VISIBLE);
        }
    }


//Option menu
 @Override
    public boolean onOptionsItemSelected(@NonNull MenuItem item) {
        int id_item = item.getItemId();



        switch (id_item)
        {
            case R.id.mnutabindx0Frag2: //show first tab and second fragment
              // select tablayout by option menu
                SelectTabUsingOptionMenu(tab_layout,0);
              // show FrameLayout with frame on it
                getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
                        new Frag_Second()).commit();
                break;

            default:return false;
        }
// Clear the viewpager visibility
        _setvisibility_FragContainers(frameLayout_fragcon,view_pager,true);
