read command is not for getting parameters. it is for for getting some input data while script is running:
$cat read.sh
#!/bin/sh
read -p "What is your name?" name
echo "Hello, $name."
$chmod 755 read.sh
$./read.sh
What is your name?John
Hello, John.

$ cat param.sh
#!/bin/bash
#while parameter's number greate then 0
while [ $# -gt 0 ]
do
#print the first parameter
echo $1
#remove the first & shift others so that 2-nd 3-rd 4-th... will 1-st 2-nd 3-rd ...
shift
done
$chmod 755 param.sh
$./param.sh q we rty uiop
