So, can you guess which one of these homebrew handheld radios has not been used in QSO yet?
Or what bands they are for?

@ftg The left one apparently has an antenna for about 900 MHz, and the tiny battery let me think of lora.

Left most one is not 900MHz, but 2.4GHz FM. Had my first #13cm band QSO's with that thing.

If you want tiny batteries, the topmost radio has a Nokia BL-5C on the other side!

@ftg And what are the other radios?

Top one is currently 70cm, but I hope to change that to 10m or 6m with some firmware.

Gray box is first edition Gekkokapula v2, so 70cm/2.4GHz dualbander.
Big slab with the 1602 display is a handheld uBITX variant, that one is not in a state for QSO yet.
Plan for that is 160m-4m RX and TX on select high bands.

And the right most is a 10m DSB handheld. That one got it's start when I wanted to work the club station with a rig made from parts at the club. 1st proto was 1.5hours to QSO.
