~~$ grep "Name" test.txt | wc -l~~

As @kojiro nicely pointed out wc is not needed.

$ grep --count "Name" test.txt

You could try the following:

For specifically Name1:

$ awk '$1 ~ /Name1/ {++c} END {print c}' FS=" " file_name.txt

For all names:

$ awk '{count[$1]++}END{for(j in count) print j,"("count[j]" times)"}' FS=" " file_name.txt

Hope that helps!
