What DOES "life cycle" mean. The cycle of life of a specific species. For example, the life cycle of a frog is, it starts off as an egg, it hatches as a tadpole, it grows back legs, it grows front legs, it moves onto land, it loses its tail, it lays eggs. Repeat. Do an image search.

No, crocodiles are not able to regenerate lost limbs or grow them back once they have been lost. Once a crocodile loses a limb, it does not regrow it.
If a starfish loses all of its legs, they will grow back. This regeneration is asexual reproduction. We just learned about that
It's different because it's in a shape of a star and if it loses one of it's legs it'll grow back.
