Answer 1

Another option using mutate and if_else() as you suggested:

library(tidyverse)

data = read_table("   id first  middle  last       Age
    1 Carol  Jenny   Smith      15
    2 Sarah  Carol   Roberts    20
    3 Josh   David   Richardson 22")
data %>%
  mutate(carol = if_else(first == "Carol" | middle == "Carol" | last == "Carol",
                         "yes",
                         "no"))

Result:

# A tibble: 3 x 6
     id first middle last         Age carol
             
1     1 Carol Jenny  Smith         15 yes  
2     2 Sarah Carol  Roberts       20 yes  
3     3 Josh  David  Richardson    22 no
