Good collection of forms in this vid from various practioners from the Liu He Quan, Xing Yi Quan and Tai Ji Quan traditions.
The first form seems to be called "Liu He Taiji" which seems to be a blend of Liu He Quan, Taiji Quan and Xing Yi Quan. The same master also performs a couple of nice Xing Yi forms straight after. This is followed by different master in yellow doing an interesting take on the Xing Yi five elements.
At 7.15 min another master comes out dressed in white does some very good Shaolin Liu He Quan. At 13 min he also does some Xing Yi but with a Liu He Quan flavor.
At 15 min another master dressed in white and performs some kind of "martial tai chi" form where every single movement is performed as a strike with fajin. Then he does a nice "Wudang Bagua Longsword" form.
Finally at 21.30 a Chinese muslim guy dressed in black rocks up and shows some extremely crisp Xing Yi.
