i've tried to use 5g toolbox to generate 5g signals and i run the NRDownlinkWaveformGenerationExample. Here is the waveform data. There are a set of zeros between effective data. What does it stand for and is it ok to delete the zeros?

In 5G downlink carrier waveform example the default configuration has been set such a way that there are set of zeros between effective data (It is only due to a smaller number of signals present in the grid). You can allocate the PDSCH transmission over whole BWP and BWP occupying complete carrier, so that you will not see any zeros.
I think you cannot delete the zero values as it is part of the transmitted signal.
Below is the link for 5G downlink carrier waveform Example.
