1.
what floor; which floor; how many floors
An interrogative used to ask which story of a building something is on, or how many stories a building has.

Disambiguation
In speech, 何階 (what floor) and 何回 (how many times) sound identical. Context usually resolves the ambiguity, but speakers sometimes clarify by saying 何階目 ('which floor') vs. 何回目 ('which time').
