All three methods are appropriate for analyzing post-facto data. 
Spearman r is a correlation coefficient that measures the strength and direction of the relationship between two variables, and can be used to analyze non-parametric data. 
H is a non-parametric test for the difference between two independent or related groups. 
U is also a non-parametric test used to compare two independent groups, when the data do not meet the assumptions of parametric tests. Therefore, all of these methods can be used to analyze data obtained after the fact.
