so that there was absolutely no way any air or gas could enter or leave the balloon, would the balloon stay afloat or would it still eventually fall?

The trouble is that the helium leaks out through the rubber of the balloon, and not actually through the hole (which is sealed with a knot).
However, if you could seal the balloon completely and still keep it lighter than air, it would of course float until such time as something changed it to heavier than air.

If the gas could not slowly escape from the balloon, then it would never fall unless other factots intervened. Theoretically, it would fly about forever, but lightning, storms, hail, etc etc would mean that eventually it would come to earth. Or at least the skin of the balloon would. In pieces.

It would still fall. Helium atoms are so small that they will go through the larger molecules of plastic of the ballon.

If the gas never escaped, it would float forever.
