1. The lines which I've coloured red are contradictory. $1, $2, $3.... are positional parameters. You can't read values into them that way.
2. Your requirement was to create directories, not files, right? touch is used to change a file's access and modification time. If file doesn't exist, it creates them.
3. Try the below script. Let us know if you have any questions.
4. Please use code tags.

Code:

$ cat test.sh
#! /bin/bash

echo "Enter 4 dir names (1st is source. Next 3 are target dirs): "
read a b c d

for x in $b $c $d
do
    if [ ! -d $x ]
    then
        mkdir $x
        cp -r ./$a/* ./$x/
    else
        cp -r ./$a/* ./$x/
    fi
done
$
$ ./test.sh
Enter 4 dir names (1st is source. Next 3 are target dirs):
test test1 test2 test3
$
$ ls -l
drw-r--r-- 3 root root   4096 Jan 24 06:27 test
drwxr-xr-x 3 root root   4096 Feb  2 04:55 test1
drwxr-xr-x 3 root root   4096 Feb  2 04:55 test2
drwxr-xr-x 3 root root   4096 Feb  2 04:55 test3

'test' was an already existing dir. test1, test2, test3 are newly created dirs, which contains all of the data contained in 'test'

rendercheck

rendercheck(1)						      General Commands Manual						    rendercheck(1)

NAME

       rendercheck - simple tests of the X Render extension.

SYNOPSIS

       rendercheck [-d|--display display] [-i|--iter] [--sync] [-t|--tests test1,test2,test3,...] [-o|--ops op1,op2,op3,...]
       [-v|--verbose] [--minimalrendering]

DESCRIPTION

       rendercheck is a set of simple tests of the X Render extension.	It is designed for authors of Render implementations in X Servers.

OPTIONS

       -d|--display display
	      Specifies the display to test against.

       -i|--iter iterations
	      Specifies  the number of times to repeat each operation before sampling results.	Some X Servers may behave differently (hardware vs
	      software rendering paths) depending on the previous operations done, so this may be used to influence the server's choices.

       --sync Enables synchronous xlib operation, for debugging.

       -t|--tests test1,test2,test3...
	      Enables only a specific subset of the possible tests.  Test names include  fill,	dcoords,  scoords,  mcoords,  tscoords,  tmcoords,
	      blend, composite, cacomposite, gradients, repeat, triangles, and bug7366.  Names must be separated by commas and have no spaces.

       -f|--formats format1,format2,format3...
	      Enables  only  a	specific  subset  of the possible formats.  Only formats listed in the server-supported format list are available.
	      Names must be separated by commas and have no spaces.

       -o|--ops
	      Enables only a specific subset of the Render operators.

       -v|--verbose
	      Enables verbose printing of information on tests run, and successes and failures.

       --minimalrendering
	      Disables copying of offscreen destinations to the window, which is on by default to provide the user with visual feedback.

BUGS

       Several	limitations  are  documented  in  the  TODO  file  accompanying  the  source.	Please	report	any  further  bugs  you  find	to
       http://bugs.freedesktop.org/.
