NGC 5024 (M53) is the most distant globular cluster (GC) with known pulsars.In this study, we report the discovery of a new binary millisecond pulsar PSRJ1312+1810E (M53E) and present the new timing solutions for M53B to M53E, basedon 22 observations from the Five-hundred-meter Aperture Spherical radioTelescope (FAST).These discoveries and timing work benefit from FAST's highsensitivity. We find that M53C is the only isolated millisecond pulsar known inthis distant globular cluster, with a spin period of 12.53 ms and spin periodderivative of $5.26 \times 10^{-20} \, \rm s \; s^{-1}$. Our results reveal theorbital periods of 47.7, 5.8, and 2.4 days for M53B, D, and E, respectively.The companions, with a mass of 0.25, 0.27, and 0.18 ${\rm M}_\odot$,respectively, are likely to be white dwarf stars; if they are extended objects,they don't eclipse the pulsars. We find no X-ray counterparts for thesemillisecond pulsars in archival $Chandra$ images in the band of 0.3-8 keV. Thecharacteristics of this pulsar population are similar to the population ofmillisecond pulsars in the Galactic disk, as expected from the low stellardensity of M53.
