Can’t tell the snail, but the other is a micro brittlestarfish which are good cleanup members. The snail is likely reef safe if it was hanging out in your chaeto

Stomatella or Collonista (or relative) would be my first thoughts for the snail, but I really can't tell from the pic - you can compare against pics of those and see if it's a match for either though.

As mentioned, the other one is a brittle starfish - should be a keeper.
