Answer 1

You can use -

library(dplyr)

df %>%
  group_by(country) %>%
  summarise(count = n(), 
            sumprofit = sum(Profit, na.rm = TRUE))

#  country   count sumprofit
#  <chr>     <int>     <int>
#1 Algeria       2    109345
#2 Australia     3     55155
#3 Hungary       2     15105
#4 Sweden        2    -10682
