Hope the goat was satisfied with the snacks...
The echeveria looks to be ok and will continue to grow normally as long as the center of the rosette, where the new leaves come in, is undamaged. Let the half bitten leaves dry out and fall off or when dried up, pulled off as the rosette continues to grow new leaves.
The other plants look like the stems were eaten away and so there will be growth elsewhere on the stem given time. Usually when one cuts a stem branching will occur or at least some new growth. The half eaten/debris of leaves should be cleared away and any disturbance of stem or soil should be righted. Any leaves that appear undamaged and whole could be left out to develop a callus and then place atop damp soil to encourage rooting of the leaf to start new plant.
The 2nd plant looks to me that it needs more light as the leaves are not as compactly arranged on the stem.
Good luck.
