I planted blackberries plants last spring my dad gave me. I noticed there are a few vines that have rooted. When can I cut them away from the main plant?

They are most likely suckers from the root stock and will have inferior fruit. Generally, you would just cut them off so the plant can focus its energy on fruiting rather than this sucker growth. You can, however, remove the suckers (with roots attached) and replant elsewhere if you want to try producing additional blackberry plants - though again, the fruit may not be as good from these growths.
