Printing first line of many files in unix

Question

Problem:

Printing the first line of 4 text files side by side

Suppose File 1

namexyz
nameabcd
So on

File 2:

producturl1
producturl2
so on

Similarly i have 2 more files.

Expected Output (Trying to create a CSV):

namexyz,producturl1,file3data,file4data
nameabcd,producturl2,file3data,file4data

What i tried (a newbie in unix):

while ((num<COUNT)) && read -u3 name && read -u4 price && read -u5 imageurl && read -u6 purl && read -u7 gdesc
do
echo "Mobiles,$1,$name,$price,,$imageurl,Amazon,$purl,Description,$gdesc" >> trial.csv
 ((num++))
done 3< names 4<amazonprice 5<imageurls 6<amazonurl 7<description

names, amazonprice, imageurls, amazonurls, description all are the name of files.
