Hi and welcome to the forum !
Grading/condition of the notes will be needed to determine the specific value. You do have some notes worth more than face value;
1954 $20 - This is a Devil's Face note - book value between $40 - $120 for a circulated example. Check the signature, it should be a Coyne-Towers. (Note: If there is an asterix before the A/E, you have a very rare note)
1974 $2 - This is a sig. change-over - Book value $5 - $10
The other notes are quite common. Not much value beyond face, sorry.
Cheers;
