Will repotting help plants that do not seem healthy?
If all else has failed, it might; but first check cultural requirements under the plant names in the plant wiki. If repotting is indicated, remove the plants from the pots, shake out the soil from the roots, and cut the roots back to healthy growth. Then replant in smaller pots. Remember: if you cut the roots back very much, the foliage must also be pruned back.
