can i download and play XBOX Series X|S and XBOX ONE games on and through my XBOX Console...

You have names mixed up. There are no consoles named the Xbox One Series S or Xbox One Series X.

The Xbox One/One S/One X all have a disc drive.

The Xbox One S All Digital Edition does not have a disc drive.

The Xbox Series X has a disc drive.

The Xbox Series S does not have a disc drive.

All the consoles can play backward compatible games. The Series S and One S all digital edition can only play games digitally downloaded.

The other consoles can play games from disc and from digitally downloaded,

I hope this clears things up for you.

It's important to know which game your friend bought.

I say this because there are currently three versions of the Series X/S game. Gta 5 Online, Gta 5 Series X/S and Grand Theft Auto V (Xbox One and Xbox Series X|S).

If he has purchased Grand Theft Auto V (Xbox One and Xbox Series X|S), which gives access to the game for Xbox One and Xbox Series S/X, he can play online with you as long as he downloads the Xbox One version, so you and he will have the same save and can play online.

If he is a Game Pass Ultimate subscriber he can download the game in the Xbox One version and play with you.

I have the Xbox one X project Scorpio, I was told that the game can be downloaded in any serie X or serie S (included mine), thanks for the help!!

Game can only be downloaded on a Series S and Series X, but not an Xbox One X. Xbox One X is not the same as a Series X.

You are misunderstanding how it works

You can pre-order games all you want doesn't mean you can download and play series s/x consoles games

Xbox one games are just xbox one games it doesn't matter which xbox one you have all xbox one games work with xbox one

This is why series consoles are labeled series not xbox one series s

Both games use smart delivery, so can only download the Xbox Series X|S version of the game on the Xbox Series X|S. If you want to play the Xbox One versions, then playing on the Xbox One is your only option.
