Hey man!
If you want to every post on page have it’s own form, you can do something like this in your acf_form() function:
acf_form(array(
'form_id' = 'form_' . get_the_ID(),
'post_id' = get_the_ID()
[...]
));
Assuming that you are going to place that inside the loop like that
while(have_posts()): the_post()
P.s.: Sorry about my english
