so i decided to choose between fluxbox or openbox.
anyway i have a lot of questions to this community:
1) is openbox and fluxbox still in active development ?
2) is JWM theme based Window manager ?
3) is there any window manager that can support plugin or applet ?
4) is there any good file browser that doesnt have a lot of dependencies(note: i like ROX filer) ?
5) is there any text editor like GEdit that doesnt have a lot of dependencies ?
I think you made a good choice. Both Fluxbox and Openbox are in very active development and have a very large user base. They might be in too active development because they are slowly getting bloated. In my bias opinion Openbox is better

What kind of answer could you expect from somebody who used Openbox for a very long time. Joking aside the big thing for Openbox is the fact that is coded in pure C. If you like to have panel, task bar and those things Fluxbox is probably better choice.
All those things can be added to Openbox but then you end up
installing another thing or two. For instance Openbox+Xfce panel is a killer combo for people who like more or less full desktop
environment.
Let me answer the rest of your questions
@2 JWM is not based on anything. It is written from the scratch.
It is really very, very good for people who like to have built in
task bar, pager, and the launching bar. It is incredible that all that is just little bit bigger than dwm which has 2000 lines of C code.
@3 What do you mean by that?
@4 Rox is not a browser. It is a file manager. There are three principle types of file managers.
i) Orthodox file managers (Norton commander type) Examples are
Deco, OFM, Midnight Commander,vifm (VI file manager) (console/xterm based) and Norther Commander, Worker, emelfm2, krusader and similar if you want to GUI.
ii) Navigational file managers (or explorer type) typical example is konqueror web-browser, xfm (X File Explorer).
iii) Spatial file managers. Examples include Xfm, Rox, PCmanFM, Desktop File Manager DFM, Nautilus file manager, Thunar, Xfiler the part of Siag suite and similar.
Then you have file managers that really could not be categorized easily like XTree file manager, Clex, pfm, (personal file manager), vfu, TkDesk.
I probably left out some interesting examples but you got the idea. The least bloated file manager is command line + commands
(ls, du, rm, mv, cp) and few filters. If you have to have a spatial file manager I really like ROX. For a Ortodox file managers I really like deco but it is not in active development and it is useless in console as it can not adjust the screen. OFM is very good code base for somebody who wants to write a good non bloated console based ortodox file manager.
Be aware that it is GPL so you will have to write everything from scratch if you prefer BSD license like me.
@5 Learn ed and vi pronto or you will regret very soon. I do NOT like VIM for me vi is nvi that comes with the base or Heirloom vi.
Emacs sucks IMHO and I have used it seriously. I even learned the Lisp because of it.
