Do you want to do this for automation? you need write ascript.
If not, you can find the exact position of each layer by
- Select the layer pressing Ctrl + T.
- Under the Photoshop menu you can find the X & Y position of layer.
So... First select 10 layer and find its position (by pressing Ctrl + T).
Next you have to move the other layer to destination file and change its position by pressing Ctrl + T and Changing the X & Y values.
I don't know what is your purpose exactly but there are lots of ways to do it. for example another way is ....
- Copy first image.
- Go to next psd file
- press Ctrl and click on thumbnail of layer 10 to make a selection around layer 10
- Press Ctrl + V or Alt +Ctrl +Shift + V to paste image in selection location.
