Can I use this chip for 5-cell charger? I have some doubts about it because there isn`t exact information in datasheet.

Yes.

The BQ2954 is a charge controller, so it can charge any number of cells depending on the external circuitry.

See http://focus.ti.com/lit/an/slua447/slua447.pdf for an example of a charging circuit that supports a higher pack charging voltage.
