The Wilcoxon signed-rank test is a nonparametric test that can be used with at least ordinal level data when the assumptions for the paired t-test cannot be met. The other options (ANOVA, Rank correlation, Kruskal-Wallis) are also nonparametric tests but do not necessarily require ordinal level data, and are not specifically designed as alternatives to the paired t-test.
