Answer 1

The part you are missing is a call to super.paint in your paint method
    public void paint( Graphics g) {
        super.paint(g);
        ...This tells the component (the JApplet) to do its default rendering before it does the custom rendering in the paint method. So the component will render your buttons before it does the rest of the paint code.
I also added an image loading method to your applet:
//  <applet code="PA" width="400" height="400"></applet>
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import java.util.Vector;
import java.lang.Math;
import javax.swing.*;
public class PA extends JApplet implements MouseListener, MouseMotionListener,
                                           ActionListener, ItemListener

    int mx, my;                             // the mouse coordinates
    Color bgc = Color.lightGray;
    Color fgc = Color.black;
    Checkbox players[] = new Checkbox[10];
    CheckboxGroup cbg;
//    Image img;
    Font font1;
    public void init() {
        // only need to create a font one time, not with every paint call
        font1 = new Font("Ariel", Font.PLAIN, 11);
        width = getSize().width;
        height = getSize().height;
        setBackground(bgc);
        setForeground(fgc);
        String s1;
        boolean sel;
        JButton jb;
        Container contentPane = getContentPane();
        contentPane.setLayout(null);
//        ImageIcon iic[] = new ImageIcon[13];
        cbg = new CheckboxGroup();
        for (int i=0; i<9; ++i) {
            s1 = Integer.toString(i+2);
            sel = (i == 7);
            players[i] = new Checkbox(s1, cbg, sel);
            players.setBackground(bgc);
players[i].setForeground(fgc);
players[i].setName(s1);
// setBounds (x=hor, y=ver, wid, hgt)
players[i].setBounds(80 + i*30, 5, 30, 20);
contentPane.add(players[i]);
players[i].addItemListener(this);
Image[] images = loadImages();
for(int j = 0; j < images.length; j++)
ImageIcon icon = new ImageIcon(images[j]);
JButton b = new JButton(icon);
b.addActionListener(this);
b.setBounds(j*30, 30, 30, 30);
