does anyone know why applyforce only works on one of my sprites? Also when I press the other sprites it also applies force to the one individual sprite. The nextTile method works fine.

It is because you only have one Body-variable, and it gets overwritten by the loop. When all sprites have been created you only know the body of the last sprite.
You must apply the force to the body associated with the sprite you click.

This is generally caused by pixel blending, which happens in the following situations:
If the texture is rendered smaller than native size, the pixels are averaged and values from neighboring pixels affect the edges of the tiles.
If the texture is rendered larger than native size, pixel values are interpolated, which also causes values from neighboring pixels to affect the edges of the tiles.
If the texture is not rendered exactly aligned to a pixel, interpolation also occurs.
So to avoid it, either make sure none of the above happens or disable texture filtering (putting it on nearest neighbor).
Nearest neighbor filtering of course doesn't look nice when the map gets scaled, so if you want to support this case you can alternatively make sure that each tile is surrounded by pixels that match the color of its edge pixels. This avoids colors from other tiles affecting its borders.
i'm trying to create something like Newton's cradle. But when one ball hits another, all balls move simultaneously in same direction. How can I decide this problem? Should i create another physical options of balls in createFixtureDef? Or I need to use some specific algorithm to transfer impuls between balls?

Unfortunately Box2D is not really suitable for this.
In my experience, you can get one or two swing-thrus to work as long as the balls are not touching each other to start with. That is, each ball starts with a very small gap between it and the neighbor on each side. This means that when they collide each collision is solved using just two balls at a time, for a total of 4 separate collisions for the impact to travel to the other side (for 5 balls), instead of solving all 5 balls as a single 'island'.
Trouble is, the positioning needs to be very precise, and after a few swings the balls stray from that, so that you end up with collisions involving more than two balls at a time. I only ever saw at most 2-3 swings work as desired...
I am developing a game in andengine.i want to move a player sprite by onScreenDigitalControl on an autoparallex background.Can anyone tell me how to do that ???? thanks
Using this code you can make player sprite moving by DigitalOnScreenControl. Also you can find many tutorials on this at http://www.andengine.org/forums/tutorials/

Bellow is the Image at run time but both are not Collide.
Just add this line after mScene.registerUpdateHandler(this.mPhysicsHandler);
mScene.registerUpdateHandler(this);
Then implement the updatehandler and add the unimplemented methods, now you can do anything in the onUpdate method, like
body.setLinearVelocity(10,10);
to make it collide with the other object.
I'm working on a little game/project and I decide to use AndEngine for it because basically the Add/Remove Physics functionality in that engine was all I need. But it seems that I have a little problem with it. I have to add like 36 different pictures on a scene and be able to remove them on select. The problem is that my images are damaged and it's not showing all the images, just the first two. Am I missing something or I'm doing it wrong? Here is what I get on my device :

Any ideas where is my mistake?
The main problem is with your onLoadResources method.
A Texture (BitmapTextureAtlas in your case) is simply a large canvas containing all small images.
Now, the method BitmapTextureAtlasTextureRegionFactory.createFromAsset(..) receives 2 numerical parameters (the 2 last parameters). These are used for the image position on the texture.
Now, take a look at what are you doing: Loading all of the images in the same position! So some images (The last image loaded - 10.png) override the others...
For more information, read about Textures & TextureRegions here.
Another problem that you have in your code - In your addFace method, when you call PhysicsFactory.createBoxBody(...) the body is created and it automatically joins your physics world, even if you don't register a physics connector between it and between the sprite, and even if you don't attach the sprite to the scene.
Only create a body when you are sure you'll need it. Otherwise, make sure you destroy it.
this.tenSprite = BitmapTextureAtlasTextureRegionFactory.createFromAsset(this.mBitmapTextureAtlas, this, "10.png", 0, 32);
this is the declration of ur image now look at the end 0,32 is same for all image you just need to change it 64,64
