Answer 1

Both dialog opens because you are invoking .show() on both dialogs. To solve this you need to change it like this.

In your original code you invoked .show() which will display the dialog. What you must do is invoke .create(). Then when you want to display the dialog invoke .show();

 AlertDialog.Builder secondDialogAlert = new AlertDialog.Builder(class.this);
 secondDialogAlert
         .setTitle("!Alert Second Dialog")
         .setMessage("Successfully opened")
         .setIcon(android.R.drawable.ic_dialog_alert)
         .setPositiveButton(android.R.string.ok, (dialog, whichButton) -> {
             Toast.makeText(getApplicationContext(), "Second Dialog Opened Successfully.", Toast.LENGTH_LONG).show();
         }).setNegativeButton(android.R.string.cancel, null).create(); // .show() changed to .create()

 AlertDialog confirmDialogAlert = new AlertDialog.Builder(class.this)
         .setTitle("!Alert First Dialog")
         .setMessage("Are you sure want to continue?")
         .setIcon(android.R.drawable.ic_dialog_alert)
         .setPositiveButton(android.R.string.ok, (dialog, whichButton) -> {
             secondDialogAlert.show();
         }).setNegativeButton(android.R.string.cancel, null).create(); // invoke create() instead of show because you have invoked it below
 confirmDialogAlert.show();
