Abstract	The follow-up timing observations were carried out for 24 pulsars discovered with the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in Commensal Radio Astronomy FAST Survey. We report their phase-connected timing ephemeris, polarization pulse profiles, and Faraday rotation measurements. With their spin periods spanning from 2.995 ms to 4.34 s, their period derivatives were determined to spread between 7.996(8) x10(-21) and 9.83(3) x10(-15) s s(-1), which imply that they have characteristic ages from 1.97 x10(6) to 5.93 x10(9) yr. It is inferred that PSRs J0211+4235 and J0518+2431 are beyond the `traditional death line'. PSR J0211+4235 is beyond the `death valley'. The death line model of Zhang et al. also cannot explain the radio presence of PSR J0211 +4235. This suggests that radiation theory needs to be improved. Besides, ten of the 22 canonical pulsars show nulling phenomena. Moreover, PSR J1617+1123 exhibits variation of emission and J0540+4542 shows subpulse drifting. The DM of five pulsars is larger than the estimated by the YMW16 electron density model, which could suggest that electron density models need updates for higher Galactic latitude regions. PSRs J0447+2447 and J1928-0548 are isolated millisecond pulsars. With their flux densities spanning from 5(1)-553(106) mu Jy, some of these new pulsars found by FAST are distant, dim, and low-. E ones and are suitable for testing pulsar emission theories.
