Of your list, I've only been to/climbed in Thailand. The climbing outside Chiang Mai is at Crazy Horse Buttress but you'll want to stay in Chiang Mai. Best place to meet partners would be the Chiang Mai Rock Climbing Adventures (CMRCA) gym in the old city (they also offer transportation to crazy horse). Not many people here from my experiences.
The climbing at Tonsai/Railey is incredible. Depending on the season, tons of people/potential partners. Cheap, dirtbag accommodations on Tonsai beach or more expensive, resorts on Railey beach. Spend at least a day deep water soloing.
There is also climbing on some of the islands, koh phi phi, koh lao liang, etc but I've never been.
Hope this helps. Enjoy!
