There is nothing official on any of this, beyond basically just two datapoints:
1) In "Metamorphosis", Kirk says that "we" are on a thousand planets and spreading. Thus the UFP controls at least a thousand planets at that point, and the context would actually indicate that mankind controls those - any worlds controlled by other UFP members would come atop that.
2) Picard in ST:First Contact, when asked about how many planets there are in the UFP, says there are "over 150". He's speaking to an ignorant listener, though, and probably answering a different question she didn't have enough knowledge to ask. Obviously, Kirk's statement would make Picard's statement a lie (even if technically 1000 > 150) unless these meant two different things: Picard appears to be listing UFP members, and indicating that one member doesn't control just one planet.
I think the number has changed throw out the original until the Voyager
but do you guys have any clear numbers?
There has been no real change to observe, because the movie ST:FC is the only one to actually mention the number of members ("planets"); no comparable number was given for Kirk's or Janeway's adventures.
We did get firsthand data on how the UFP was founded through Archer's adventures, though, and learned that there were either four or five founding members in the UFP - the humans, the Vulcans, the Andorians, the Tellarites and (only seen mentioned in obscure props from the movie ST:Generations) the Alpha Centaurans. Since Zephram Cochrane in "Metamorphosis" is defined both as being "of Alpha Centauri" and fully human, the fifth founding member culture could be just a facet of the human culture, and therefore commonly ignored. Then again, the Vulcan culture being a member doesn't mean all Vulcans would be UFP citizens (the Romulans most definitely are not, and they are Vulcans biologically). Perhaps Alpha Centauri survives as a political entity independent of "mankind" even in the 24th century?
in star trek enterprise it showed interesting races were forming the new state that we never meet again
All the shows and many of the movies feature UFP members that never reappear. This is basically possible with 150 members, as only less than 50 are ever made explicit, although the "revolving door" portrayal would be easier to buy if there were a bit more members.
In the original they only brought us terrain colonies in some planets as far as am watching now in the second season
The original show never mentioned anybody but humans as being members of the Federation - until showing a bunch of Ambassadors of varying species in "Journey to Babel", and indicating that they all came from Federation member cultures. No colony of Vulcans or Tellarites was ever mentioned, but we can conjecture that such things did exist even back then. Or then we can choose to conjecture otherwise. (Yet Archer did visit Vulcan offworld settlements explicitly "earlier"/"later" on!)
Of course there are the Vulcan planet one of them
what else??
This list is probably the most reliable, or even erring a bit on the side of caution:
