The sooner you can get to those apples the better.
Applesauce....you can use just straight apples with just enough water in the pan to keep them from sticking & cook em down to a sauce. You may need/want to use a tater masher to help them along. You can also add some sugar if you want or even some cinnamon, nutmeg, ground cloves, etc for extra spice flavor.
Apple Butter....IMO, the only difference between sauce & butter is the length of cooking time. For apple butter, using whatever amount of sugar & spices (as mentioned above for sauce) just simmer for 2 or 3 hours until it's as thick as you want it.
Apple Pie Filling...you can 'can' apple pie filling by using apple slices with sugar & spices, heated & put in jars & processed in a WB canner for about 15 min for pints & 25 min for quarts. When using the canned filling for a pie, the apples will be softer in the pie than if using fresh.....but still good
Dried Apples.....just slice the apples in roughly the same sized slices (1/4 inch?) & toss with some lemon juice &/or sugar &/or spices & spread out in a single layer in a dehydrator until fairly dry. Probably atleast 2-4 hours, maybe longer. Any moisture in the apples will hasten decay or mold, etc.
If you don't have a dehydrator, you can spread them out on a cookie sheet & put in your oven on the lowest setting with the door propped open a bit for air circulation. You'll just have to check them periodically & turn them over now & then so they can dry evenly. I don't have a dehydrator anymore (mine broke down & haven't replaced it) so I've been using my regular oven for any drying. It's not perfect but it works. If you have a convection oven that's even better since the fan helps to circulate the air.
Decorations or Crafts...I've used Red Delicious apples because of the star shape of the core when sliced, but I think any apple can work. If you have any decent whole apples, just make slices thru the apple like you would slice a tomato or something then sprinkle with cinnamon or other above spices on both sides and dry until pliable. Using a paring knife or even a screwdriver, kinda poke a small hole near the edge and thread some string, yarn or ribbon & tie a knot so you have a loop to hang the spiced apple slice. I've done this at Christmas time & hung these (and orange slices too) on the tree, the wreath on the front door, etc. It makes your house smell so Christmas-y & fruity too and with it on the wreath on the door even guests get a whiff before coming inside.
Just sharing some ideas.......
edited to include if you can the pie filling, when using it later all you have to do is have your crusts ready and pour in your own homemade filling. (sorry, just thought to add that just in case you (or anyone reading) wasn't sure about the process)
