I have some questions regarding the 747D "domestic"
1. How many were produced?
2. Are there any 747D's other than Japanese companies?
3. What is its Max range?
4. Is it equipped with the same engines as the normal 747's?
5. Does it carry the same number of passengers as the normal one?
6. does it fly with the same speed?
Can some one please get me the info, thanks.

The range for 744D is only about 2000NM. It does not have the same MTOW. It will not fly as far as the normal 744 unless upgraded.
ANA has converted one of its 747-481D to 747-481. Which required 1 month of upgrade to increase the MTOW. Engine is also changed. Even though the engines are the same GE CF6. Engine were derated for 744D as there is much less weight. Hence changing to regular 744 require engine be changed as well.

Correct. Due to the fact that the winglet only helps during cruise, winglets has no benefit on the 744D. Majority of the 744D flight are less than 1 hour and spent most of its time climbing and decending.

All true, the domestic 747s (of all versions) have downrated engines, less fuel capacity I believe in the form of deleted center fuel tanks. There would be no reason to even differentiate the -D model from anything else if the only difference was more seats, any 747 can have any seat config the operator chooses; downrated engines, less fuel capacity, lower MTOW and less range are unique to the -D varieties. They are designed to carry more pax over short hops, thus negating the need for high MTOW or standard range. When you are flying 747s within an area only about the size of California, you sure dont need all the extras to make it heavier and wear it out with the many daily cycles they rack up.

Quick side note-
Just recently ANA has delivered two of their standard (low cycle but high airframe time) 744s to Boeing for conversion to 744D configuration. Basically they're taking off the wingtips and strengthening the landing gear, while reworking the interior. Pretty clever way to maximise the airframe's life.

Are you sure? Cause I heard it's the other way around. They are sending 744Ds to be converted to normal 744s because their cycles are getting high, but airframe time is relatively low. Which way is it?

You have outdated information. From Boeing's website:
SEATTLE, May 15, 2001 - All Nippon Airways (ANA) announced today that it has selected The Boeing Company to convert two ANA 747-400 airplanes from its international configuration to its domestic configuration. Boeing Airplane Services will perform the conversion work for both airplanes at its Wichita Modification Center in Wichita, Kan.
Boeing will convert the airplanes from a three-class, 367-seat configuration to a two-class, 569-seat layout. The reconfiguration primarily involves removing the winglets and installing wingtips, as well as modifying the cabin interior with new passenger and attendant seats, in-flight entertainment systems, galleys, lavatories, floor coverings, closets and stowage units. With a new interior layout and modified wing structure, ANA's 747-400s will be ready for high-cycle, increased density, domestic routes in Japan.
