I'm looking for some information on the details shown in an app's page on the Google Play.
Thanks for the help,

Does a user get a chance to rate the app after each version change?
Users can update and change their ratings at any time, but they cannot have a unique rating for every version of your app. At any point of time, one user can only have one rating.
Does the reviews has an expiration date?
No.
Can spam reviews be removed from the total app score rating?
If enough users mark it as spam or flag the review, Google will remove it.
If a user rate the app after an update - does it replace his previous review?
Yes
Can I reset the app rating and delete all user reviews?
This is only possible if you unpublish the old app and publish it again under a new package name. You cannot delete the old reviews and recent your rating while using the same package name.
Does the Google Play count downloads once per Google account?
I'm not sure about this, and can't find any documentation on it, but I think they count downloads once per account, not device, as one of my paid apps has been bought less times than its been installed.
If a user uninstalls and re-installs an app - does it gets counted again to the total installs number?
It may show up in the total installs for a while, but Google Play adjusts these metrics, and it will remove the double count and count it only once when the adjustment happens.
Can I change the app's name/publisher once it is published on Google Play?
Yes and yes.
