You have to reform your question to be an actual question before someone can answer it. A counter circuit's output depends on the previous state when it is 'clocked'. So the output might be something like 0010, when the previous output was 0100. Then the next one after 0010 could be 0001. Or it might count the other way, depending on how configured.
A ripple counter is a counter in which state transitions of one or more flip flops are triggered by the outputs of other flip flops in the circuit. If all flip flops in the counter are triggered by a common clock pulse, then the counter is called a "synchronous counter". a ripple counter is a counter that will ripple through the information sequentialy. .
Ring counter A ring counter is a shift register (a cascade connection of flip-flops) with the output of the last one connected to the input of the first, that is, in a ring. Typically a pattern consisting of a single 1 bit is circulated, so the state repeats every N clock cycles if N flip-flops are used. It can be used as a cycle counter of N states. Johnson counter A Johnson counter (or switchtail ring counter, twisted-ring counter, walking-ring counter, or Moebius counter) is a modified ring counter, where the output from the last stage is inverted and fed back as input to the first stage. A pattern of bits equal in length to twice the length of the shift register thus circulates indefinitely. These counters find specialist applications, including those similar to the decade counter, digital to analog conversion, etc

Johnson counter is a ring counter, which is a type of counter composed of a circular shift register. Johnson counter provides many shift registers and ring counters.
