You can refeed whenever you want to and redo the fast after you have had equal number of days to refeed as many days of your fast. You will gain/ benefit no matter how long a fast you do. Sometimes tongue becomes pink before true hunger returns and vice versa. In any case fast should be broken in any case when true hunger returns.
I am concerned about your plan to break your fast when you meet friends, the pressure to eat may make you eat wrong foods and too much food. If it was only a few day fast it would have been ok, but you are fasting for 24 days so receding has to be very slow and with juices only.
Please do not drink anything but water during your fast, it is not ok to drink teas. You cannot put anything in your mouth, no toothpaste, mouth washes, nothing.
