Yes, those euphorbias should be easily propagated by cuttings, just cut any section that you want ( 8 inch will be a decent size), let the cuttings air dry and callused over in a bright shade area ( 5 days to 2 months, whenever you like ), then plant the cuttings in a gritty soil mix, don't water them in the first 10 days, then gradually give them small amount of water like once a week when the soil completely dry. You can have a lot of cuttings from those 2 plants, just try with 1 or 2 pieces to experience the process.

For the first photo of the lactea, instead of cutting 1 section, you can also cut like 2 to 3 inches below the line /wire that you use to tie the plant. Then you will have a nice big green clump of new plant.
