I would like to program my ESP 8266 WiFi module. But I don't have an FDTI right now is there any way to use Arduino Uno as FDTI Programmer then use ESP without it.

Yes. Tie the reset pin on the ISP connector low to keep the ATmega328P in reset, then you can connect pins 0 and 1 to the ESP module to communicate using the Uno's USB-UART bridge. Since the pins are labelled from the perspective of the '328P, connect TX to TX and RX to RX.
