Short version, based on what you have, bring:
tourniquet
chest seal
quick clot
trauma dressing
triangular bandage
space blanket
Ibuprofen AND Tylenol
Everything else is fluff. If it will not save a life, or enable self rescue, why carry it. Ditch the pouch and use a 1 qt Ziploc.
Probably to late for this trip, but get you Wilderness First-aid, or even better, Wilderness First Responder.
More complicated version, and ignoring recommending other products.
In the US, Good Samaritan laws give a lot of protection. The short version is, so long as there is no compensation for you assistance the standard you are held to is gross negligence (i.e. not doing anything obviously harmful) instead of the standard of negligence (i.e. not doing anything that a reasonable person would not do). It is a little more complex, but anyone interested can read into it.
Personally, I would leave the chest seal, trauma dressing, and tourniquet. With tape (if you carry duck tape or such) and a space blanket you can fabricate a chest seal (or a trash bag for that matter). You can use a space blanket to cover a burn and minimize fluid loss and hypothermia (talking large burns). A triangular bandage can be a pressure dressing (especially if combined with an item of clothing) as well as a sling and a tourniquet when combined with a stick. Some things depend on personal skill and designed one trick ponies are easier to use than improvised solutions and most people will screw up an improvised tourniquet causing more harm than they do good. So what I do may not be correct for you.
Sutures require skill to prevent scaring and knowledge to keep from creating a bad infection as well as to identify other potential complications. If you need sutures, just get to a professional. You have about 24 hours before it can no longer be closed successfully to do that in. If anyone wants to learn more about suturing look up Practical Plastic Surgery for Nonsurgeons, this is a free book. You would still need to be able to assess for injured tendons and other things that would cause even an ED doc to refer a patient to orthopedics or surgery.
Tylenol and ibuprofen can be used together and I would carry both. The combination might be the difference between walking out and needing someone to come get you. Just take each in accordance with the label.
Just use clean drinking water and wash wounds with large amounts of it. Alcohol and all other antiseptics cause harm and delay healing. Ideally use pressure when you wash it, a syringe works, but if you use a hydration bladder you can also just sit/kneel on it to get a pressurized stream. There is not evidence (at least last I checked) to show that sterile water irrigation results in fewer infections than tap water.
