Hey Kara,
Congrats on being in escrow! I definitely understand that home inspections can be an influx of information, especially as a first-time homebuyer. It does help to have an extra set of opinions, and Greg Scott provided solid input.
For (1) and (3), water intrusion and wood deterioration are not uncommon for older homes. Having a pest inspection done is helpful as well because it notes the areas of dry rot, fungus, termite damage, water damage, etc. and give you actual bids on how much it would cost to repair.
(6) is not a major repair, as Greg mentioned.
For (2), (3), (5) -- any foundational notes like these I would agree to consult with a structural engineer or expert, as it likely suggests in the home inspection. If you haven't done so already, I would ask the inspector transparently how severe this sloping/grading/foundation is affected and if it would be a major expense. What I like to do as an agent is to get the inspector on the phone (sometimes with my client) and inquire with the inspector that exact question, along with any other areas of concern in the home that you feel is a major issue.
Hope this helps and best of luck!
