Is there a church near or next door to the stadium? I often hear church bells.

Yes, but it is not from the church. It is a team sound effect.

That's the time's up alarm sounding on the Astros' season.

Yes there is. I believe it is Cumberland Church. Hope that helps

Ominous sound effect to intimidate the opposing batters.

Yes

No..that's the beginning of an ac/DC song

Not really close, no atleast 2miles. The bells are a sound effect and the beginning of Hells Bells by AC/DC

Im really not sure

Not sure of that

Yes it is
