Does grout ever go bad?...once it starts to lump inside the bag, is that sign that grout is bad/unusable, can you turn it back into powder somehow?......also the excess grout removed from between the tiles, is it reusable?...

Grout, like any form of cement, is cured when mixed with water because of a chemical reaction that uses the water as a catalyst. So, you can't just take grout that has been cured, grind it back up, and re-use it. It will never re-cure.
For the same reason, you should not use the grout from the bag that is hardening. It's hardening because moisture has gotten in the bag and the grout started curing. If you try to use this grout, it will never cure right. The result will be places where the grout is granular or powdery, instead of a nice solid grout.

The grout is turning solid because it is absorbing moisture from the air. It should not be reused once it reaches this state. It weakens the integrity of the grout, and will have a higher instance of flaking and cracking.
You cannot reuse the grout from removed tile.
