I'm comparing two groups in a large dataset. For some of the variables, such as # of arrests, the following 5 choices are available: 1, 2, 3, 4, 5 or more

This seems like ordinal categorical data. Can I just use the 5 choices on their own to compare across groups, like doing a chi squared analysis and regression models? Or should I be doing any sort of dummy coding or watching out for anything else?
