Can I use this 1.8" TFT LCD to make it show graphic? Or all the TFT LCD can display graphic?

Yes, you can draw graphics on this display.
You can draw graphics on any display that is (individually controllable) pixel based, i.e. it mentions a resolution, something like 128 x 160 in the specs. They are referred to as "Graphic" displays. Common types include STN, TFT, OLED.
The other common type of display is usually referred to as "Alphanumeric", and lists a spec like 16 x 2 (characters x lines) With these you can only display letters/numbers.
Most Alphanumeric displays are STN (Super Twisted Nematic) based.
The Renesas R61581 is an intelligent display controller that handles all of the high bandwidth tasks needed to refresh the display. The control interface allows a microcontroller to send commands and data to load the in-built video RAM. It is an ideal choice to drive with a medium scale microcontroller.
Much of the datasheet refers to connecting the controller to the LCD glass, which you won't need to worry about. The controller has a multitude of host (microcontroller) interface options, but the simplest and easiest way to start is probably by configuring it for 8-bit parallel data access (so long as the display gives you access to the IM pins to set this up, otherwise use what's provided by the display interface). The datasheet includes a comprehensive command reference.
When you can initialise the controller and write a few pixels, then you're up and running and can develop your graphics code incrementally.
From what I have seen in other TFT display datasheets it's the voltages used to drive the gate of the pixels. Supply the VGH and VGL pins with the typical voltage.
Edit: As for AVDD, that's the positive supply voltage for the analog circuit.
