Am i using が right

So we just starting using が in Genki and to my understanding it’s the particle that is used to identify the noun that is doing an action, but I guess I’m a little confused on how it should be used. An example I have is:

あなたの学校に何がありますか。
Would responding with:
(学校に)クラブと学生のラウンジと図書館がのあります。
Be correct and being using が properly
