Oxalis megalorhiza / carnosa.

you can´t graft seedling to an unmature seedling, let them grow up and then graft to the mature M. geometrizans stock.

agree with O. trollii
M. elongata
C. gigantea

agree with Echinopsis / Trichocereus pachanoi, or peruvianus or similar...

Trichocereus bridgesii / lageniformis.

Thanx for the great habitat pics!

Beautiful!

hi,
I agree on the Monadenium
but disagree with Delosperma, for me it look like Crassula mesembryanthemoides.

it does look like it could be a Consolea starting
a new trunk,have to wait and see if it puts on
some pads.
I agree. Some Consolea and also Opuntia species form new trunk from the rooted pads.

Nice shots! Thanx for sharing them...also for the info

Great looking plant!
