is it possible to connect 5 cameras in one fpga? can somebody help me,. 
it can process all of them simultaneously? thank you for reply,.

Sure. Did you know there's FPGAs with a 5 digit price tag? You might 
need a couple of those...or just one for 20 bucks...
Come on, what the heck were you thinking? What kind of camera? What kind 
of processing? Give out some more information and people will be able to 
actually help you.

Other than that, you can do pretty much anything in FPGAs. It's just a 
matter of how much you want to spend on them. And a matter of your 
hardware design skills of course.

Use ethernet cameras (GigEVision) and buy a cheap ethernet switch.
Then you can connect more than 100 cameras.

(you did not say anything of interface or what processing means)

It is possible. But there's a vast variety of implementation options. 
You need to follow this check list first:
- What kind of sensor interface? (parallel, LVDS, MIPI?)
- How much data is generated (resolution, fps)
- Where does the data go
- How does the data compress

For multi cam solutions, you'd typically use sensors using a serial fast 
LVDS to solve the connectivity problem (5 parallel buses might make you 
run out of I/Os already).
Then you need to multiplex the streams into one or compress them in 
parallel and multiplex them later.
Most crucial point is storing the data. So make a bandwidth calculation.
If you need 5x720p30, you'll have to be thinking about massive parallel 
compression and huge FPGAs plus a 2 year's job.

These are the experts I like. They cannot even describe the Problem 
rather than estimate effort and demands. Looking forwar to the outcome.
