can i use these on pi 4b ? i would like to avoid stacking the diff pi boards

Yes, the Pi4 uses the exact same interface pinout as the Pi3 so this will work just fine (I can say this conclusively as well as I have this ribbon extension cable and both Pi3 and Pi4 boards). That also goes for any of the screw terminal breakout shields if you should wish to use any of them as well with your Pi4 (the B+ just indicates revision level and enhanced onboard specs, but pinout remains the same). Just be careful to properly align the pins with the header connectors at each end when using this cable as you can misalign the pins when installing this cable and keep note of which is pin #1 when attaching shields (I like to mark pin 1 on one end of the connector with a black line using a permanent marker. You can also verify by testing for the 3.3V, 5V, and ground rails to verify proper orientation of your connector and shield.

Can I buy two and chain them together for distance?

yes -- but why not simply buy a longer cable (there are lots of companies that sell these cables)

Can i connect the screen to a raspberry pi 4 whit this cable? i need the screen to be a little further than just placed over

If your screen was previously connected to the GPIO, then this will be an extension and should work fine. I used it to distance an audio hat away from the processor on the Pi and it worked flawlessly.
