Gravity is the force that keeps things from flying off into space.
Only if the object is homogeneous, i.e. the mass is uniformly distributed. If the object is lumpy, or has thick spots and thin spots, then the center of gravity isn't related to the geometric shape. Consider a see-saw with a light kid on one end and a heavy kid on the other end. The geometric center is the mid-point of the board, but the center of gravity is closer to the heavy kid.
Friction is like a force that happens when two things rub against each other and resist moving. It's the reason it can feel hard to push a heavy box across the floor or why sliding down a slide is slower than falling straight down.
Magnetic force is like a magical invisible power that certain objects have, making them want to stick together or push each other apart. It's what makes magnets attract certain things like paper clips and repel others.
