I have trees against a blue sky,
The blue sky was pasted in as a background.
However I need to get rid of the white amongst the leaves from the original image.

When I select the white, it picks all the white in the total image, not just among the leaves.
How can I just select white among the leaves?
I tried using quick mask, and selected the total leaves area, and avoided the rest of the image.
But I cannot select the white among the leaves.
How can I do this?

Ahhh very tricky. Youll have to make a general selection of the tree, save the selection, then select all the white, and subtract the inverse of the saved selection. That should give you just the white among the tree. You can clean up any stray  bits with your lasso tool before deleting. Its alot harder than it sounds.

Another solution that may or may not work for you is to select the whole tree by selecting the blue background and inverting it. Copy the tree and paste it onto a white background in a new canvas. Then using your magic wand with appropriate tolerance and non-contiguous selecting, select the white and invert. You should now have the whole tree, with little or no white depending on your tolerance setting.

I cut out the sky and roof line from the top of my photo and pasted it into a new layer.
Then in new layer I delete out the white sky.

In original layer, I delete out total selection
But when I paste back into layer 1, the graphic is not aligned with origianl image.
i.e. i have to manually move it and match it up.

How can I keep the aligment of layer 2 excatly to match layer 1?
