All are jungle cacti. Top right, segments of your other clippings. Top left, Hatiora salicornioides. Bottom right, Rhipsalis, maybe cerescuela (very dehydrated, but if it isn't crinkly it could very well revive).

Bottom right, Rhipsalis mesembryanthemoides (mesem-brie-an-the-moy-dees). Love both the name and the plant. Fast grower, makes white flowers all along the stem. Easy as the others to root.

Just keep the unrooted cuttings in slight contact with good soil that is slightly damp. Keep warm, out of direct sun until roots form. You don't say where you live, but rooted specimens of these, need direct sun in the winter and shade in the summer for most of continental U.S.. Bloom is mostly in the winter, small berries form from pollinated flowers.

Dzitmoidonc- thx for the info. Very helpful. I'm in So. Cal where we have summer weather at the moment. I'll make sure they get light and protect in summer where temps are sometimes 100+
