Can I delete apps from my Google Play Store available apps?
Yes, you can delete both free and paid apps from your Google Play Store available apps. You can do this by launching the Google Play Store, tapping on your profile icon, and selecting Manage apps & device. Tap on the Manage tab. You can now checkmark all the apps you want to delete and tap on the Trash icon.
Can I transfer purchased apps from iPhone to an Android device?
No, you will not be able to transfer purchased apps or subscriptions from an iPhone to an Android phone, or vice versa. If you have a subscription, it’s best to cancel it on the old phone and subscribe to the service again. The only exception is if you paid for the subscription directly, without going through the Apple App Store or Google Play Store.
Can I reinstall purchased apps on Android?
Yes. Once you find an old purchased app, you will be able to install it on your new phone again. No need to pay twice!

Using the account page on the web you can filter for just apps from all purchases. https://play.google.com/store/account?purchaseFilter=apps. On an android device open the link with a browser instead of the Play Store. The Play Store app cannot filter apps from other purchases.
From the web you can also install apps on any devices connected with your account.
How can I find out when I purchased an app? I've been using smart launcher for years and I was curious about when I initially bought it. Is there any way to sort alphabetically to find it easily?
There currently is no way to view the list of options for in-app purchases in the Google Play store itself. However, Google Play does actually know what in-app purchases are available to any given application because all in-app purchases have to be registered in the Google Play Publishers Console before the In App Billing (IAB) platform will function for those items.
https://developer.android.com/google/play/billing/billing_admin.html
Each in-app product has to be registered in each application for which it applies. The process to set up a single product is quite involved. Google Play does have the information available but they don't, at this time, make the list of items available for purchase to users of the Google Play store. That is up to each application. In addition, making that information generally available to users might lead to upset users. For example, a developer decides to add a new highly-requested feature that they initially decide will be $1.99 but then decide later on to raise that price to $2.99 just before releasing it. Those expecting to get it at $1.99 because they saw it early on might be upset at that change. Also, if a developer utilizes the IAB Products API to synchronize a product list from another tool, it might push products into Google Play that are not actually used in the app itself.
In-App purchases come in a wide range including unlocking features, making donations, adding bonus content and buying specific items but they all fall under the single permission.
I've also seen them broken down as: Permanent enhancements to the app, Expendable updates (i.e. extra lives or tokens), Subscriptions, and Auto-renewing subscriptions
If the type of in-app purchases are not listed in the description of the app or in any reviews for the app I would ask the developer via email. Other than that you would have to download it to find out.
When viewing an application on the Google Play Store (for example, Sygic GPS Navigation), it says underneath the Install button "Offers in-app purchases". Unfortunately, I don't see a way to view the in-app purchases unless I download the app.
Is there any way to view an application's In-App Purchases without downloading / installing the application?
you can find order information by GPA-id in the order management UI - https://play.google.com/console/u/0/developers/NNN/orders/
then you can copy purchase token and use it for fetch the order using API https://developers.google.com/android-publisher/api-ref/rest/v3/purchases.products/get
You can't get the purchase information by GP order-id directly, but you can get the info by purchase-token.
There's a place to find the purchase-token, open google play console - order management - order detail by order-id, on top of the page, you can find the button to get the purchase-token.
Using web-api https://developers.google.com/android-publisher/api-ref/purchases/products/get, you can get the details.
