JimboZA:
As you can guess i try run 4 BPM085 sensors on arduino uno
Well I can't speak for other members, but no, I would not have guessed that in a zillion years :~
I should write " AS you can guess NOW" 
MattS-UK:
Sorry, I don't have particular experience with the particular sensor you are using.
It looks like your code is crashing elsewhere, so the execution point never reaches your simple print statement - Pretty much what PaulS just said. I am currently re-writing a sensor library after I found a state which could cause the library code to enter an end less loop.
It stands a chance there may be more to reading from multiple sensors than 'just' setting a pin high/low. You might have to reinitialise the sensor, for instance. Exactly what you need to do may well depend on the library code and when you don't do it right, the code crashes within the library.
As ever, best start getting something simple working with one sensor. Then the same simple thing with two and only then attempt to scale up.
Tnx for pointing to right direction. It started work (well at lest printing to serial monitor) then I wrote:
void loop()
{
digitalWrite(6,HIGH); // missing line
Looks what Arduino needed sensor to set all values. Without that line it was no active sensors to do... afraid to write absolute nonsense, but think it's calibration and counting temperature, pressure.
But still.. as MikeGrusin at sparkfun wrote:
You can’t normally connect multiple BMP085s to the same I2C bus since they all have the same I2C (Wire) address. However you can run additional I/O pins to the XCLR input on each BMP085 to turn all of them off (LOW) except one (HIGH), and then talk to that one.
Remember that the calibration data is different from each device. The example code doesn’t handle this by default. You might work around this by re-grabbing the calibration data each time you want to do a reading on a different BMP085, or re-writing the code to save all the calibration data from all connected devices. I know of no existing sketch code to do this, but Google and see what you can find. Good luck!
So to make it work right I'm need more brain, more luck, more help. I'll try my luck with google. If it fails I'll make new post.
PaulS:
Post ALL of your code now.
My code is p0rn you wont able to handle it 
. I tested many things on it(lcd, some other sensors, some lcd code, like bars) and didn't delete a thing, just commented unused lines... most of them. but original code was this:

Get pressure and temperature from the BMP085 and calculate
altitude. Serial.print it out at 9600 baud to serial monitor.
Update (7/19/11): I've heard folks may be encountering issues
with this code, who're running an Arduino at 8MHz. If you're
using an Arduino Pro 3.3V/8MHz, or the like, you may need to
increase some of the delays in the bmp085ReadUP and
bmp085ReadUT functions.

Tnx to Owner of code for sharing it, if you know him say tnx from me
Again thanks everyone for help. I'm really happy what my for loop and if statements was ok. As I sad it's my hobby, I'm carpenter so in my job here is nothing even close to coding.
