If you put the public SSH key on each of the servers, then you will be able to have password-less authentication to run the commands. Do you know how to generate the keys and what to do with them?
If you are running as the root user, then you will need to make sure that the /etc/ssh/sshd.conf configuration file permits root login. There are a number of options to consider and balance against the risks.
I'm afraid that there is no easy way to get them onto each server - it will be a manual task, but the investment of time in a one off action.
Note
When you are adding your users, you will need to make sure that their UID is unique too. Some servers will object if you try to add a user with a specific UID that already exists. You could get away with not specifying the UID, but then if you are NFS sharing files (or moving them keeping original permissions) then you will all sorts of problems because files are owned by the UID not the alphabetic userid.
I agree with jlliagre that you would be better to use NIS (historically also known as YP) or LDAP. Once set up, that would cut down the administration effort.

I wish to fire certain set of commands on different servers using single script on one of the server. The problem is that these servers only allow ssh session. telnet to these systems is blocked.
Is there any way i can do this as rsh does not works.

atf-sh
ATF-SH(1) BSD General Commands Manual ATF-SH(1)
NAME
atf-sh [-s shell] -- interpreter for shell-based test programs
SYNOPSIS
atf-sh script
DESCRIPTION
atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library.
atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL. atf-sh executes the inter-
preter, loads the atf-sh(3) library and then runs the script. You must consider atf-sh to be a POSIX shell by default and thus should not
use any non-standard extensions.
The following options are available:
-s shell Specifies the shell to use instead of the value provided by ATF_SHELL.
ENVIRONMENT
ATF_LIBEXECDIR Overrides the builtin directory where atf-sh is located. Should not be overridden other than for testing purposes.
ATF_PKGDATADIR Overrides the builtin directory where libatf-sh.subr is located. Should not be overridden other than for testing purposes.
ATF_SHELL Path to the system shell to be used in the generated scripts. Scripts must not rely on this variable being set to select a
specific interpreter.
EXAMPLES
Scripts using atf-sh(3) should start with:
#! /usr/bin/env atf-sh
Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh. Instead, you have to hardcode
the path to atf-sh in the script and then use the -s option afterwards as a single parameter:
#! /path/to/bin/atf-sh -s/bin/bash
ENVIRONMENT
ATF_SHELL Path to the system shell to be used in the generated scripts.
