You may need to check your firewall configuration, or turn it of using "service iptables stop". However, Telnet and FTP are legacy protocols used in the last century and obsolete. Unless you have a very specific need for FTP I suggest not to bother with it anymore.
Only ssh, tcp port 22, will be allowed to accept incoming connect by default. Apparently you have Putty (ssh client) and WinSCP, which supports SFTP and SCP. If you can use SSH to connect to your machine, SCP and SFTP will work too. If you cannot establish a SSH connection with your server, check your network routing and tcp/ip configuration on the client and server. If you run any kind of machine virtualization, check the virtual network adapter type.
Did you perform a minimal install? I suggest you reinstall the system using the default software selection. Alternatively, configure yum to access the repository on the installation DVD according to the OS release notes and type "yum install openssh-server". Provided your TCP/IP network works, SSH will work too.
