One approach is to define a helper function that matches for a specific animal, then bind the columns to the original frame.

We can use
stri_replace_all_regex to replace your
color_1 into integers together with the arithmetic operator.
Here I've stored your values into a vector
color_1_convert. We can use this as the input in
stri_replace_all_regex for better management of the values.
I have a database with columns
M3. These M values correspond to the values obtained by each method. My idea is now to make a rank column for each of them. For
M2, the rank will be from the highest value to the lowest value and
M3 in reverse. I made the output table for you to see.

With your show samples, attempts; please try following
awk code. Since you are opening files all together it may fail with infamous "too many files opened error" So to avoid that have all values into an array and in
END block of this
awk code print them one by one and I am closing them ASAP all contents are getting printed to output file.

library(tidyverse) example %>% pivot_longer(cols = starts_with("es"), names_to = "type", names_prefix = "es_", values_to = "es") %>% pivot_longer(cols = starts_with("pwr"), names_to = "pwr", names_prefix = "pwr_") %>% filter(substr(type, 1, 3) == substr(pwr, 1, 3)) %>% mutate(pwr = parse_number(pwr)) %>% arrange(pwr, es, type)

You may define a function
FUN(n) that creates a data set as shown in OP.
I am trying to tidy up some data that is all contained in 1 column called "game_info" as a string. This data contains college basketball upcoming game data, with the Date, Time, Team IDs, Team Names, etc. Ideally each one of those would be their own column.
