Help with where to plant some shrubs

I've got the following shrubs to move either because they're not thriving where they are or they have become crowded.  

But I can't decided how to set them out in my garden.  I have got the space to create a new plot to put them all in but I can't visualise what they would look like all together.  Would it even work?  Can anyone help me with a really nice way of laying these out please?   Are there any rules of thumb to follow?
