Once you already have your phyloseq object df_family, you can use the function estimate_richness from phyloseq. You can then join the sample meta data to this data frame of alpha diversities. Finally, you can use ggplot2 directly to customize your plot accordingly, e.g. to put different sample groups (here SampleType)…
