What does it mean if a number occurs more than once in a row of a stem- and-leaf plot?

If you have two 10's  and three 25's in a list for a stem and leaf plot, it will look like this:

1 | 0 0
2 | 5 5 5

A number occurring more than once in a stem-and-leaf plot just means the number is repeated, and should be added to the plot. 

Hope that's what you needed

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
