Help understanding the use of あります


I understand that あります is used for presenting or describing the location of
things but I was unsure of how it is being applied in these two sentences:

> あなたの学校に何がありますか。

Am I right in assuming that this is saying 'what is at your school?'

> この教室にだれがいますか。

Am I right in assuming this is saying 'who is in that classroom?'




> Am I right in assuming that this is saying 'what is at your school?'

Yes.

> Am I right in assuming this is saying 'who is in that classroom?'

No, since この means "this", the answer is

"Who is in this classroom?". Not "that".
