can i replace 100v 100nf ceramic capacitor with 50v 100nf in an amplifier it will be safe?

that depends on the voltage being put into it.
the 100v / 50v is the maximum the cap is designed to handle.

The suitability question may be more than what DC voltage the part can withstand. Depending on the type of ceramic dielectric, specifically its temperature and voltage coefficients, the applied DC voltage may affect the part's capacitance. "COG" would be unaffected; "X7R" can be affected as much as 10% or 20%; "Y5V" or "Z5U" can be affected (reduced) by as much as ~80%.
