Each player should be assigned its own hp bar to work with. Create the hp bar for each player before creating the player. When creating the player, pass the hp bar it is to use to it. Have the player retain the hp bar in a reference field. The following will most probably need some modifications; but the idea behind what to do should be apparent: 
/**   in subclass of world   */

// in constructor or prepare method
HpBar hpbar1 = new HpBar(); // creating healthbar
Player1 player1 = new Player1(hpBar1); // creating player

// repeat for player2


/**      in class of player     */

// instance reference field
private HpBar hpBar;
private Actor playerTouching;

// the constructor
public Player1(HpBar bar)
{
    hpBar = bar;
}

// in act or method it calls
Actor player = getOneIntersectingObject(Player2.class);
if (player != playerTouching)
{
    playerTouching = player;
    if (playerTouching != null && playerTouching.getY() < this.getY())
    {
        hpBar.setValue(hpBar.getValue()-20);
    }
}

i tried your code i just implement the if logic from your code : this my code look like : 
public void hitBadGuy()
    {
        Actor badguy = getOneObjectAtOffset(0, getImage().getHeight()/2+4, Veylectra.class);
//        Actor badguy = getOneIntersectingObject(Veylectra.class);
        if(badguy != null && badguy.getY() >= this.getY())
        {
            World myWorld = getWorld();
            Stage1 myworld = (Stage1)myWorld;
       HealthBar healthbar = myworld.getHealthBar();
            if(touchingBadGuy == false)
            {
                healthbar.loseHealth();
                touchingBadGuy = true;
                //Greenfoot.playSound("punch.mp3");
                if(healthbar.health <=0)
                {
                    setRotation(90);
                    Greenfoot.delay(delayAmount);
                    setRotation(180);
                    Greenfoot.delay(delayAmount);
                    setRotation(270);
                    Greenfoot.delay(delayAmount);
                    setRotation(0);
                    Greenfoot.delay(delayAmount);
                    setRotation(90);
                    Greenfoot.delay(delayAmount);
                    setRotation(180);
                    Greenfoot.delay(delayAmount);
                    //Greenfoot.playSound("youlose.mp3");
                    setRotation(270);
                    Greenfoot.delay(delayAmount);
                    setRotation(0);
                    Greenfoot.delay(delayAmount);
                    Greenfoot.delay(50);
                   // GameOver gameover = new GameOver();
                    //getWorld().addObject(gameover, getWorld().getWidth()/2, getWorld().getHeight()/2);
                    //Greenfoot.playSound("gameover.mp3");
                    getWorld().removeObject(this);
                }
                
            //}

        } else
        {
            touchingBadGuy = false;
    }
}
}

You already have the Veylectra object as an Actor object called 'badguy'. You should get the healthbar from it. Something like this: 
Veylectra player = (Veylectra)badguy;
HealthBar healthbar = player.healthBar;
