You can try defining a function like this:

function! Increment (...) range
let i = a:firstline
let pattern = a:0 ? a:1 : '\d\+'
while i <= a:lastline
call setline(i, substitute(getline(i), pattern, '\=submatch(0)+1', ''))
let i += 1
endwhile
endfunction

Then you can call Increment on a range and it will increment all numbers matching the given pattern (or the first encountered number if no pattern is given). For instance, the first lists could be incremented with

:'<,'>call Increment()

(in Visual mode) and the second with

:'<,'>call Increment('#\s*\zs\d\+')

(Don't forget `\zs'!)

That was just off my head, though, and simpler solutions may exist.

Best,
Paul
