These are small items and won't block the closing since they are not considered material changes.
1. Kitchen sink disposal. Has the disposal been checked during inspection? If not, you don't have a baseline and there is nothing you can do. If yes and it was working fine, and now it doesn't, you can ask for a settlement from the seller, and if they don't, get a professional estimate and take the seller to small claim court as an option, assuming you've an addendum to have the seller maintain the property as is after mutual acceptance.
2. HOA letter. Assuming the cleaning isn't in the contract, and the required time to clean is after closing, Seller doesn't have to do it. If the cleaning is required before closing, Seller has responsibility. Again, you can get a professional estimate and take it to small claim court. (< $5000).
