Finding out which record is "Up Next" isn't possible with just a formula field I'm afraid. To get the upcoming meeting you're going to need to create a linked field to another table and do calculations to figure out which meeting is the upcoming one
"All Done" and "Not Yet Read" are easily done with formulas though!

IF(
IS_BEFORE(
DATETIME_PARSE(
{Date in Text},
"DD/MM/YYYY"
),
TODAY()
),
"All Done",
"Not Yet Read"
)
(If your date is in a Date type field you can just remove the "DATETIME_PARSE" bit)

Thank you so much! The formula worked.
