["Account File", "Bank File", "Study Case", "Overall Status"].each |group|
   system "scp", group, 'user@server1:/tmp'
end

Assuming all these "groups" are in a single directory you can also do

Dir["#{dir}/*"].each |group|
   system "scp", group, 'user@server1:/tmp'
end

Then, if you want to process the output of the command you should look 
into IO.popen.

Kind regards
