Ok, I found most of missing names of Thai players from picture above, which I found also HERE. It's 2nd stage of choosing roster, from 38 players they chose 30 and add a MB (Chutima). I tried to recognize as many players as possible, but I still have 5 question marks there.
According to photo of Thai NT's wide roster we have players (in order):
1st: Wanna Buakaew (L), Wilavan Apinyapong (OH), Pleumjit Thinkaow (MB), Nootsara Tomkom (S), Onuma Sittirak (OH)
2nd: Malika Kanthong (OP/OH), Tapaphaipun Chaisri (OH/OP), Amporn Hyapha (MB), Thatdao Nuekjang (MB), Piyanut Pannoy (L), Pornpun Guedpard (S), Ajcharaporn Kongyot (OP), Sontaya Keawbundit (OH)
3rd row: Kaewkalaya Kamulthala (MB), Kuttika Kaewpin (OH), Kittiyakorn Phansamdaeng (S), ? (OH), Jarasporn Bundasak (MB), ? (OH), Tikamporn Changkeaw (L), ? (S)
Bootom 2 rows: Yupa Sanitklang (L), Supamool Rasamee (OP), Wantichaya Luangtonglang (OH), ? (OH), Sineenat Phocharoen (OP), ? (MB), Soraya Phomla (S), Hattaya Bamrungsuk (MB), Em'Orn Phanusit (OP/MB), Chutima ?. (MB)
Can someone from Thai users (I guess You can do it Tony ) help me with these question marks? - they're 3 OHs, MB and Setter. I'm also not sure about few others like Tikamporn, Khwanjira and Supamool - are they these players Thai language is so hard
For WCH we'll probably see mostly players from first 2 rows, maybe adding either Kaewkalaya or Wantichaya or Yupa.
In Italy I see this 14 (of course staringline-up is rather obvious and we won't see backups so often...):
S: Nootsara, Pornpun
OP: Malika, Ajcharaporn
OH: Wilavan, Onuma, Tapaphaipun, Wantichaya
MB: Pleumjit, Thatdao, Amporn, Kaewkalaya
L: Wanna, Piyanut
Simultaneously we'll have Asian Games in Incheon (Korea), so there should play others which won't find place in WCH roster:
S: Kittiyakorn, Phomla
OP: Em'Orn (also MB), Phocharoen, Supamool (also OH)
OH: Sontaya, Kuttika, ?, ? (here we have question marks, because there are players which I couldn't recognize )
MB: Jarasporn, Khwanjira
L: Yupa/Tikamporn
