In Assembler we have 16 General purpose Registers and we also have Floating point Registers. Are there separate physical registers present for FPRs or we use the same 16 GPRs as FPRs?

Suggest you read the zArchitecture Principles of Operations SA22-7832-03 which describes the different types of registers available.
