If I have Minecraft on my Xbox One S, will I be able to get it on the Windows 10 store for free or for the actual price?

I have Minecraft (It's just called Minecraft not Minecraft Xbox One Edition) and I just got a new computer. I signed in with my Microsoft account, and I see that Minecraft Windows 10 Edition is about $30. Would I have to pay for that, or not sense I had Minecraft on my Xbox?

No, the xbox and computer minecraft are two different things. You would have to pay for a mojang account to get it on the computer. Sorry!

Yes

No

Minecraft isn't one of the "Play Anywhere" games where the Xbox One and PC versions share the same license. You do need to buy it again if you want to play it on both.

Minecraft: XBox One Edition is DIFFERENT than the Windows 10 Edition of Minecraft, so you will have to purchase it separately.

However, if you choose to purchase the Java version of Minecraft for PC (at $27 US), Mojang throws in a key for the Windows 10 Edition for free (you have to claim it through the Mojang website).

No. The Xbox One S and Windows 10 are two different things. Also, the editions are different. So you'd have to buy it again on the Windows Store.
