Instead of using anonymous inner classes for event handling, Use named classes.
Create an instance for this class as eventhandler and keep the variable
somewhere such that it is accessible from inside the Frame.
Now for each textbox set this as event handler for keytyped events
As

textbox.addKeyListener(myEventHandler);

Now to access the textboxes as arrays you can just declare them as

TextBox txtBoxes[]=new TextBox[10]; //create references
for(i=0;i<10;i++)
    txtBoxes[i]=new TextBox(); //create the text box

To identify from where the event occured, you can use the getComponent()
Method of KeyEvent.
