Hello deniseg509 and welcome! I can't answer about the currency, but the stamps you show are extremely common and have very little monetary value. The real value of course will always be memories of the person who gave them to you. You can safely put the stamps in a stock card for storage. By the way, the bottom ones are not postage stamps, but rather cinderellas (labels) of some type.
As an approximate answer for the currency, I found a listing on
ebay for your $5 note where the seller is requesting $65, but with currency (as with stamps) condition is everything and prices vary widely depending on same.
