Linux Bash script question, please help me figure out, Thank you!

So this project require me to use "grep" command to find out these things in the HW1_Data.txt:

I have already solved it:

1: grep -c '[0-9]$' HW1_Data.txt

2:grep -c '^[^aeiouAEIOU]'

3: grep -E -c '^[A-Za-Z]{12}$'

4:grep '^[0-9]\{3\}\-[0-9]\{3\}\-[0-9]\{4\}$' HW1_Data.txt

5:grep '^303\-[0-9]\{3\}\-[0-9]\{4\}$' HW1_Data.txt

6.grep -c '^[aeiouAEIOU]\w*[0-9]\b$' HW1_Data.txt

7.grep -c 'geocities\.com$' HW1_Data.txt

But I am confuse about how to turn my answer into the Bash script and take user input? I am new to this.

It seems it will use other files to test my command, but I don't know how to do this. Please help
