Stacking Sprites and destroy bottom all fall

I am creating a chopping tree game. I have created 5 sprites staked on top of each other. When the ax hits the bottom one it is destroyed. I can’t get the 4 other to fall down to chop them. How do I have the other sprites fall? I am trying to stack like tetris blocks.
Any help is appreciated.
Here is what I have done:

add acceleration_y to the sprites on game update.

That only works on 2 blocks. 3 blocks stay in position. I don’t know how to change the y on blocks that already have been created.

did you try using this way with a ‘for element value of array of sprites of kind’?
