I tried to write an example clearer:

Code:
date_form1=$(date +'%y-%m-%d') # Variable date format : YYMMDD
date_form2=$(date +'%Y-%m-%d') # Variable date format : YYYYMMDD

height_file1=$(du -h /home/$date_form2/* | sed -n '1p' | cut -c 1-4)
name_file1=$(du -h /home/$date_form2/* | sed -n '1p' | cut -c 6-)

height_file2=$(du -h /home/$date_form2/* | sed -n '2p' | cut -c 1-4)
name_file2=$(du -h /home/$date_form2/* | sed -n '2p' | cut -c 5-)  

height_file3=$(du -h /home/$date_form2/* | sed -n '4p' | cut -c 1-4)
name_file3=$(du -h /home/$date_form2/* | sed -n '4p' | cut -c 5-) 

height_file4=$(du -h /home/$date_form1/* | cut -c 1-5) 
name_file4=$(du -h /home/$date_form1/* | cut -c 6-) 

height_file5=$(du -h /home/$date_form1/* | cut -c 1-5)
name_file5=$(du -h /home/$date_form1/* | cut -c 6-) 

height_file6=$(du -h /home/file6-$date_form1.tar.gz | cut -c 1-5) 
name_file6=$(du -h /home/file6-$date_form1.tar.gz | cut -c 6-) 

disk_used=$(df -h | sed -n '9p' | cut -c 23-27)
disk_available=$(df -h | sed -n '9p' | cut -c 29-33)
disk_percent=$(df -h | sed -n '9p' | cut -c 35-38)

fichier1="/home/$date_form2/file1" 
fichier2="/home/$date_form2/file2"
fichier3="/home/$date_form2/file3"
fichier4="/home/$date_form1/file4"
fichier5="/home/file5-$date_form1.tar.gz" 
fichier6="/home/$date_form1/file6" 

affiche () {
if [ $name == "$fichier1" ];
then
	: (I wish nothing, No display)
else
	echo -e "\nDate :   $date_form2\nFile :   $name_file1\nHeight : $height_file1\n" ;
fi

if [ $name == "$fichier2" ];
then
	: (I wish nothing, No display)
else
	echo -e "Date :   $date_form2\nFile :   $name_file2\nHeight : $height_file2\n" ;
fi

if [ $name == "$fichier3" ];
then
	: (I wish nothing, No display)
else
	echo -e "Date :   $date_form2\nFile :   $name_file3\nHeight : $height_file3\n" ;
fi

if [ $name == "$fichier4" ];
then
	: (I wish nothing, No display)
else
	echo -e "Date :   $date_form2\nFile :   $name_file4\nHeight : $height_file4\n" ;
fi

if [ $name == "$fichier5" ];
then
	: (I wish nothing, No display)
else
	echo -e "Date :   $date_form2\nFile :   $name_file5\nHeight : $height_file5\n" ;
fi

if [ $name == "$fichier6" ];
then
	: (I wish nothing, No display)
else
	echo -e "Date :   $date_form2\nFile :   "$name_file6"\nHeight : $height_file6" ;
fi

}

declare -a missing
for name in $fichier1 $fichier2 $fichier3 $fichier4 $fichier5 $fichier6
do
     [[ -e $name ]] || missing[${#missing[*]}]=$name
done

if (( ${#missing[*]} == 0 ))
then
	echo -e "\nDate :   $date_form2\nFile :   $name_file1\nHeight : $height_file1\n" ;
	echo -e "Date :   $date_form2\nFile :   $name_file2\nHeight : $height_file2\n" ;
	echo -e "Date :   $date_form2\nFile :   $name_file3\nHeight : $height_file3\n" ;
	echo -e "Date :   $date_form2\nFile :   $name_file4\nHeight : $height_file4\n" ;
	echo -e "Date :   $date_form2\nFile :   $name_file5\nHeight : $height_file5\n" ;
	echo -e "Date :   $date_form2\nFile :   "$name_file6"\nHeight : $height_file6" ;
else
          
	affiche ;
	echo -e "\n\nMissing: " ${missing[*]}

fi

	echo -e "\nDisk Used : $disk_used\nDisk Available : $disk_available\nDisk Used In Percent : $disk_percent\n" ;

exit 0 ;

Its output :
Code:
Date :	2016-09-19
File :  /home/16-09-19/file1
Height : 100K

Date :	2016-09-19
File :  /home/16-09-19/file2
Height : 160K

Date :	2016-09-19
File :  /home/16-09-19/file3
Height : 4.0K

Date :	2016-09-19
File :  /home/16-09-19/file4
Height : 236K

Date :   2016-09-19
File :
Height :

Missing:  /home/16-09-19/file6

Disk Used :  39M
Disk Available : 185M
Disk Used In Percent : 18%

I took off the file 6 for provoke the function "affiche", like you note, it misses display of the file 5 and on position of file 6 it's blank.

Me, I would like :
Code:
Date :   2016-09-19
File :  /home/16-09-19/file1
Height : 100K

Date :	2016-09-19
File :  /home/16-09-19/file2
Height : 160K

Date :	2016-09-19
File :  /home/16-09-19/file3
Height : 4.0K

Date :	2016-09-19
File :  /home/16-09-19/file4
Height : 236K

Date :	2016-09-19
File :  /home/16-09-19/file5
Height : 236K

Missing:  /home/16-09-19/file6

Disk Used :	39M
Disk Available : 185M
Disk Used In Percent : 18%

or
Code:
Date :	2016-09-19
File :  /home/16-09-19/file1
Height : 100K

Date :	2016-09-19

Height : 236K

Date :	2016-09-19
File :  /home/16-09-19/file5

File :  Missing:  /home/16-09-19/file6
Height :
