I have read a few of the articles related to the Language Oriented Programming paradigm. Therefore, I concluded that LOP paradigm can let programmers be more productive because of it’s extensibility.
Are there any programming languages that are already implemented LOP or in development status?

As was mentioned, language oriented programming will refer to a DSL.
This may summarize what you are trying to express:
When you have to solve a complex problem, first choose – or, if
necessary, develop – a language that is most appropriate for the
problem. Then, implement the solution in this language.
which I found in:

There are many languages that will help you create a DSL, such as Groovy, Ruby, Scala and F#.
You can write internal and external DSLs in these languages, and these languages have constructs to help the programmer create a DSL more easily, such as using parser combinator so you can more easily create a compiler or interpreter for your language.
This will make it easier for the end-user to write their own programs, in the language they are used to, so they won’t realize they are writing a program, just expressing what they want done.
So, you could have something like:
order 10 cartons of milk from Soya and deliver them to store 23 delivered on 4/1/2013.
It would be obvious to the user what they are doing, and as long as they follow some rules you express the language can be very expressive.

I assume you’re referring to Meta Programming System, which is for creating domain-specific languages. Of course, you can create your own DSL with any other programming language. Indeed, many functional programming languages (including Haskell and Lisp) have tutorials for building simple interpreters. And you can always build your own parser with Lex and Yacc.
