there are different kinds of RAMs like SDRAMs ans ROMs like EEPROM on FPGA boards , why ? FPGAs have these memories inside of them , why there are more Memories on Boards?

Even your mobile phone and your tablet or your PC have different kind of memories: RAM, ROM, FLASH, Memory-Cards, Memory-Sticks, ... > FPGAs have these memories inside of them , why there are more Memories > on Boards? Memory inside a FPGA is usually SRAM based. SRAM is volatile memoy and it is expensive memory (lots of transistors per bit). Memory outside the FPGA can be larger, cheaper and it could be permanent/non-volatile.
