Let the number of monkeys be A, the number of pandas be B and the number of lions be C, then:

1, the first condition, it is easy to know, 2c < x (under c < 1), c < x2.

2. the second condition is 3a < x and a < x3.

3. the third condition is 4b < x and b < x4.

4, the fourth condition, we can see that c < 2b.

Then 2c < 4b < x

Suppose x=32, the maximum value of b is 7, the maximum value of c is 13, and according to 3a < x, the maximum value of a is 1b, making a total of 3b.

So if x=3b, the maximum value of b is 7, the maximum value of c is 13, and the maximum value of a is 9. The total is 29.

Therefore, if x=29, the maximum value of C is 7, the maximum value of B is 13, and the maximum value of A is 9, then b= 13, c=7 and a=9 satisfy all the conditions of the topic.

A: There are 9 monkeys, 13 pandas and 7 lions.

So the answer is: 9,13,7.
