I would like to get these line numbers of a different window without moving to that window.

line('w0')
line('w$')
line('.')
line('$')

As for the first two, we can use getwininfo([winid]) which returns a list including 'topline' and 'botline'. Is there any function or some workaround as for the last two?

As a partial answer, for line('.'), you can get the buffer number associated with a window with winbufnr(nr) (carefull to pass the window number and not the window id) then pass it to getbufinfo([expr]) and get the lnum entry :

getbufinfo(winbufnr(nr))[0]['lnum']

Thanks to @Luc Hermitte, we can get the last line number with

len(getbufline(winbufnr(nr), 1, '$')

which gets all the lines of the buffer as a list of strings and returns its length.

Old original answer

Can't tell how to get line('$') without moving to the actual window. But we could achieve it with a function that restores the current and previous visited window, than get any line(expr) :

function! WindowLine(winnr, expr)
 let curr_window = winnr()
 let prev_window = winnr('#')
 exec a:winnr . 'wincmd w'
 let line = line(a:expr)
 exec prev_window . 'wincmd w'
 exec curr_window . 'wincmd w'
 return line
endfunction
echo WindowLine(2, '$')

  With len(getbufline(winbufnr(nr), 1, '$') we can obtain the number of the last line in a given buffer. It will be a lot more efficient than any solution that switches context (and that could also trigger autocommands)

patch 8.1.1418 introduced :h win_execute() :

call win_execute(winid, 'let l:num_lines = line("$") | let l:current_line = line(".")')

It's fast, it has no window related side effect.
