Is they are way to make script that copy the files that have same names in a sub directory 
?

The advantage is easy access.
What you suggest looks exactly what i am after, but need assist with it: Get name of file to copy. Test if file already in destination directory. If no, copy it. If yes, create new subdirectory and copy file to subdirectory instead
I don't mind copy all the files from the list in a new destination preserving the folder tree as well, but again i need help because don`t know how to preserve the directory tree.

Sounds like a mess.
For example. it seems you have at least four copies of DeskTop.jpg so you would need at least three subdirectories to preserve all the files. What are you going to name those subdirectories so you can tell which files are where?
As other poster suggested, you could also append something to prevent duplicate file names. But sounds confusing.
Why do you want to copy all the files together into one directory in the first place? What's the advantage?
If there is a good reason to do this, I'm sure it could be done: Get name of file to copy. Test if file already in destination directory. If no, copy it. If yes, create new subdirectory and copy file to subdirectory instead.

install
install(1B) SunOS/BSD Compatibility Package Commands install(1B) NAME
install - install files SYNOPSIS
/usr/ucb/install [-cs] [-g group] [-m mode] [-o owner] filename1 filename2 /usr/ucb/install [-cs] [-g group] [-m mode] [-o owner] filename... directory /usr/ucb/install -d [-g group] [-m mode] [-o owner] directory DESCRIPTION
install is used within makefiles to copy new versions of files into a destination directory and to create the destination directory itself. The first two forms are similar to the cp(1) command with the addition that executable files can be stripped during the copy and the owner, group, and mode of the installed file(s) can be given. The third form can be used to create a destination directory with the required owner, group and permissions. Note: install uses no special privileges to copy files from one place to another. The implications of this are: o You must have permission to read the files to be installed. o You must have permission to copy into the destination file or directory. o You must have permission to change the modes on the final copy of the file if you want to use the -m option to change modes. o You must be superuser if you want to specify the ownership of the installed file with -o. If you are not the super-user, or if -o is not in effect, the installed file will be owned by you, regardless of who owns the original. OPTIONS
-c Copy files. In fact install always copies files, but the -c option is retained for backwards compatibility with old shell scripts that might otherwise break. -d Create a directory. Missing parent directories are created as required as in mkdir -p. If the directory already exists, the owner, group and mode will be set to the values given on the command line. -s Strip executable files as they are copied. -g group Set the group ownership of the installed file or directory. (staff by default.) -m mode Set the mode for the installed file or directory. (0755 by default.) -o owner If run as root, set the ownership of the installed file to the user-ID of owner. ATTRIBUTES
