This will get you the 5th line
Code:
sed -n 5p infile

To check for "string" in 5th line:

Code:
awk 'NR==5&&/string/ {exit 1}' infile || echo "Found it!"

Code:
word=$( awk 'NR==5 { for(i=1;i<NF;i++)
    if ($i ~ /string1|string2|string3|string4|string5|string6/)
        { print $i; exit }
    }' infile )

Word will be blank or first of your 6 strings found on the 5th line
