A magnet is a substance that is made of iron. The molecules in it are arranged in a way different than most magnets which is why the magnet has a tendency to attract materials more. Instead of the fridge magnet having a distinct north or south pole attraction, the fridge magnet has both alternating. This actually gives a stronger force of attraction.
When the magnet is brought in contact or brought close to the fridge, the force between the north and south poles of the body of the fridge and the magnet attract each other, and the alternating poles on the magnet attract as well, giving that extra attraction.
A magnet sticks to a refrigerator because the refrigerator door is made of a ferromagnetic material, such as steel. The magnet and the refrigerator door have opposite magnetic poles, causing them to attract and stick together.
The term "refrigerator magnet" is ambiguous and may refer to any number of types of magnets. However, typically a refrigerator magnet is going to be relatively weak and made of the most inexpensive materials available. Hard refrigerator magnets are likely iron. Flexible refrigerator magnets are made of bonded ferrite powders; barium ferrite is among the most common. In general classification, a refrigerator magnet is a permanent magnet.
A magnet sticks to a refrigerator because the metal of the fridge is ferromagnetic, meaning it can be magnetized. When a magnet is pressed against the fridge, it creates a magnetic field that aligns with the refrigerator's magnetic field, causing the two to stick together.
No, a magnet in front of a refrigerator is not an example of friction. Friction is a force that opposes the motion of an object when it is in contact with another object. The magnet sticking to the refrigerator is due to magnetic forces, not friction.
If the refrigerator magnet can't hold a piece of paper against the refrigerator, it may be due to the forces of gravity overcoming the magnetic force produced by the magnet. The weight of the paper pulling it down is greater than the magnetic force trying to hold it up.
the magnet is supporting weight. I say yes.

it is a magnet and you just stick it to your fridge

The refrigerator isn't actually a magnet, it it simply made of metal which magnets can then stick to.

No, a refrigerator magnet is not a permanent magnet. Refrigerator magnets are usually made of soft magnetic materials that become temporarily magnetized when in the presence of a magnetic field, allowing them to stick to the refrigerator. Permanent magnets, on the other hand, retain their magnetization over time without the need for an external magnetic field.
