Who is the root user in Ubuntu or on any Linux based distribution?

The user having the real user id of 0 is the root user. You can check UID by grep "root" /etc/passwd or more precisely grep "root" /etc/passwd | cut -d: -f3 .

Is by default the root password for every system running Ubuntu is same?

By default the root account is disabled in Ubuntu (you can enable it, although it is not recommended), you can use sudo to impersonate root.

Many documents over WEB supports not to enable root login manually as it has been said that let all applications should run on User level or with Administrative accounts only?

Thats logical.
