Rpi connected to a monitor showing habpanel in fullscreen, project!

I wonder if I could make use of these spare Rpi 3B´s ´ve got, and then a 22" FullHD montiors connected to the monitor using HDMI. Then run some software unattended which will show happanel from my openhab server on the monitor in FullHD (full screen)?

Sure, most browsers, including Chromium, support running in kiosk mode. Just install a full Raspbian with the graphical environment, configure it to make Chromium to start automatically in kiosk mode and set your HABPanel as the home page.

A nice to have feature would be, if I could use this Rpi as an audio sink from the openhab server, and passing on voice TTS. (I´m using Google TTS). I know this would require speakers to the monitor or perhaps using the audio output of the Rpi.

I believe that HABPanel will act as an audio sink, though I don’t know if you can specifically target a specific HABPanel. You may only be able to send audio to ALL HABPanels.

Another nice to have feature would be, if this Rpi could be a chromecast device as well

You can make it an AirPlay device easily. You can make it an DNLA/UPnP receiver easily. But you can’t make it a Chromecast receiver as far as I’m aware, though OrangeAssist - Google Assistant Integration might work. I’ve never been able to get this fully working so I don’t know for sure.

and a Google Home device, so it could receive voice commands. But this is probably not an easy task, and most probably impossible. At least the Rpi would need an mic.

This part isn’t so hard actually. See [WIP] Google AIY Voice with openHAB. Keep in mind, that won’t make it a fully functional Google Home, but it will do the things you are asking for.
