I have a 13inch Macbook Pro 2018 and LG Ultrafine 5k
It seems only Akitio Node Pro have two usb-c port can plug both rmbp and 5k
I wonder will the GPU work if I plug the 5k into the second usb-c port?
thanks!

From what I remember, and smarter folk can correct me if wrong, while it may work the display will not be powered by the GPU. So you can daisy chain the 5K but it won't be the same as driving the display directly from the GPU like with the black magic. 

I use the 5K in Windows and can accelerate games on it despite no direct connection to eGPU.

The second Thunderbolt 3 port on the enclosure can only provide DisplayPort passthrough from the Mac's iGPU/dGPU. The eGPU does not accelerate the external monitor directly in this arrangement. A 5K monitor such as the LG UltraFine actually robs bandwidth from the eGPU when daisy-chained. I tested connecting two 4K monitors to the AKiTiO Node Pro as well as a 5K monitor via a Thunderbolt 3 to dual DisplayPort adapter. It's best to connect the UltraFine 5K to another TB3 port rather than daisy-chain to the enclosure.

What can I do to accelerate the LG 5k ?
Only blackmagic eGPU can do this job?

Only the black magic can accelerate it directly but both windows and macOS have software options to choose any gpu, however there are performance hits due to the non directness.

Can I ask a question?
Is there  a hug gap between BlackMagice RX580 and Vega20 in 2018 Macbook Pro?

I just acquired a 5K display, however, I'm having issues getting it to work in Windows when the dGPU is disabled. I have the eGPU connected to one port of the 2017 MacBook Pro and the LG display connected to the other port. It just feels like the iGPU is not able to power the 5K display.

I also tried connecting the 5K display only without the eGPU and that too doesn't work. It seems like it would only work if the internal Radeon card is enabled. May be the Intel integrated graphics is not powerful enough. My eGPU is an AMD card, which is why I have to disable it, and I also disable the right ports on my Mac.

Of course the intel iGPU is not powerful enough for a 5k disply.  You must use a dGPU or better an eGPU.
Why would you disable the right ports of your Mac? You don't remove two wheels of your sportscar, do you?
