Is the GRE required for a second masters degree?

It depends on the program and the university. Some universities may require the GRE for all graduate programs, while others may only require it for certain programs, such as those in STEM fields. Additionally, some universities may have different GRE requirements for students who have already earned a master's degree. It is important to check with the specific program and university to which you are applying to find out what the GRE requirements are.
