The Wilcoxon signed-rank test is the nonparametric equivalent of the paired-samples t test, as it is used to compare two related samples and assess whether their mean ranks are significantly different from each other. The Kruskal-Wallis H test and Mann-Whitney U test are nonparametric tests, but they are used to compare independent samples rather than paired samples. The chi square test is also a nonparametric test, but it is used to analyze frequencies of categorical data rather than continuous data.
