If two people with clocks are moving linearly past each other, the
faster they are moving relative to each other, the slower the other
person's clock appears to be ticking.

If one person with a clock is accelerating in a circle at constant speed
near another person with a clock, who is not accelerating, the clock
going in a circle will appear to be ticking slow to the other person, and
that other person's clock will appear to be going fast to the person
who is accelerating.

Stay in the same spot relative to what? All linear motion is relative.
Every measurement of position and speed is relative to something else.
You can measure the speed of two bodies relative to each other, but
neither body is moving faster than the other.
