OK - in your first batch of pictures (numbering them 1-5 left to right)
1) no idea
2) azalea (don't be surprised if it doesn't flower next year - unless you physically remove the old flower heads each year (and just the flower heads) they don't).
4) not sure but it's probably an acer (aka japanese maple)
5) hellebore but I don't know which kind -there are a lot and they are also known by names such as christmas rose or lenten rose
