Thank u for your response, i heard some graphics cards have 1 VGA , 1 DVI and 1 HDMI ports. As u told (DVI-VGA) if i convert HDMI-VGA, results total 3 VGA i think. is it possible? in that case of 'working together' i actually meant that i need to display different things through these three ports. Eg:- if i sets a virtual class room, i need one display to the admin, one to the teacher and the 3rd one to projector for students at the same time.

Your question is a little confusing.

Some video cards have a VGA output, and a 2nd one available via a DVI to VGA adapter if the DVI connection is DVI-I (not DVI-D).

Thus you'd need TWO such cards to run three VGA monitors. You wouldn't get a SINGLE SCREEN, but you could use a different program with each one.

If by "work together" you mean a single screen experience with the same GAME or PROGRAM split between all three monitors, then NO I don't think you'll have much luck with that.

A graphics card with 3 outputs should be able to run 3 independent display devices.

You will need to convert at least two of the outputs to VGA.

VGA is VGA
DVI-I can be converted using this http://t0.gstatic.com/images?q=tbn:ANd9GcRDAMGJPYh78zNk...
DVI-D requires an active converter like this http://tinyurl.com/mcbenfj
HDMI requires an active converter like this http://www.lindy-usa.com/img/news/38191xxl.jpg
