No
No, stacking magnets does not make them stronger. Magnets have a set strength based on their material and size, and stacking them does not increase this strength.

No, adding magnets together does not increase their strength. Magnets have a fixed strength based on their material and size. Placing them together may change their magnetic field, but it does not make them stronger.
Yes, storing magnets close to other stronger magnets can cause them to be demagnetized or have their magnetic properties weakened. Additionally, strong magnets can attract each other with such force that they can chip, crack or shatter if not handled carefully.
One answer is iron, nickel, and cobalt. But many others are alloyed with them to make them stronger.
My answer id they have different shapes and colors.
Yes, because electromagnets can lose their magnetism.
Some magnets are stronger than others, making them harder to pull apart. For strong magnets, you can pull the magnets sideways to get them apart.
Yes (and often are).
Rare earth magnets, such as neodymium magnets, are much stronger than traditional magnets like ferrite magnets. They are also more expensive and are made with elements from the lanthanide series of the periodic table, making them rarer and harder to produce. Rare earth magnets can retain their magnetization over a longer period of time compared to normal magnets.
