Keep in mind that what you've displayed is an unbalanced dataset. And that
some of the of contrasts you're after (if I followed your description
correctly) would involve Satterthwaite weighting of between and within
variances.
Have you considered forgoing ANOVA and just use Student's t-test for the
specific comparisons of interest?
Type -help ttest- for syntax for paired and independent samples.
Alternatives could be the Mann-Whitney U / Wilcoxon rank-sum (-ranksum-) and
Wilcoxon sign-rank(-signrank-) tests.
