I read this howto and have the following questions:
Is this like the GPU passthrough VFIO (you need two monitors and two different graphic cards, and a motherboard which supports IOMMU feature)?
Or is possible to assign a virtual GPU to guest which can run graphic apps (games or apps needing direct card access) using only one card (of course if GVT-g is supported)?

Sounds like this is very much a work in progress - redhat.com/archives/vfio-users/2018-April/msg00019.html.

Q1: Is this like the GPU passthrough VFIO (you need two monitors and two different graphic cards, and a motherboard which supports IOMMU feature)?
Looking at this slide from this video on Youtube titled: Intel GVT-g: From Production to Upstream - Zhi Wang, Intel, it looks like you have to have a motherboard that supports IOMMU.
  
Also looking at this slide, it looks like you just have to have a single GPU. Regarding your last question.
Q2: Or is possible to assign a virtual GPU to guest which can run graphic apps (games or apps needing direct card access) using only one card (of course if GVT-g is supported)?
It looks like the guest OSes through QENU will use VFIO MDEV via their GFX drivers internal to them.
