Which is right ? 哪个是对的? 1. 一间商务套房 还是 一个商务套房? 2. 一间标准间 还是 一个标准间?

both ok my dear

Both "一间商务套房" and "一个商务套房" are correct in Chinese. Similarly, both "一间标准间" and "一个标准间" are also correct. In Chinese, both "间" and "个" can be used as a measure word for rooms, depending on the situation and personal preference, ie, some people might prefer using "间" for hotel rooms, while others may use "个". So, it really depends on the individual's preference or the norm of the specific context.

i think is 一间商务套房和一间标准间

一间商务套房
一间标准间

一间商务套房和一间标准间

“间”。you can use "间“ to express almost all quantifiers about "room".
For example：一间屋子、一间厨房、一间套房、一间粮仓。
