Hello Duranni, welcome!

May I ask what kind of pages the stamps are in or on? It looks like to me that there are strips of something (adhesive? Glue?) behind them? Is this a photo album of the sort that uses a sticky background to hold the photos down? If that is true then please get the stamps out of that as soon as possible as that kind of page will ruin the stamps. That glue is very hard to remove.
Otherwise, if that is not the case (I worry a lot), then I agree with the above statements, the stamps mostly seem like common ones that are not valued very highly. The stamps that have nicks and tears and pieces missing have lost any value they may have had money-wise but are sometimes valuable for study of postmarks, varieties, colours, etc.
Try to get closer with the camera for a close-up and also to remove the plastic on top of the stamps so we can see them clearly. Oh, those lines of sticky glue worry me.
Stamps are sometimes, well, most of the times, valued by their collectors for their value of being fun to collect, not solely for any dollar value. They are little pieces of art and culture and history and need sorting out. That is why they are collected.
