We were waiting for Ali for more than 2 hours by the time he arrived to to the station

Explanation:

I'm pretty sure this is the answer

we will be waiting for ali for more than 2 hours by the time he arrives at the station

Explanation:

because the sentence is saying he will arrive at the station it means he is going somewhere. but it says once he gets there. so instead of to, like he is still going to that place, it is at. because assuming he will be there when he is he will be at the station.
