You can easily spend 30 minutes at each memorial/monument. The mall is about 2 miles long so plan time walking the whole thing.

The White House/archives are both a little ways off the actual mall. The archives almost always has a huge line of people there so plan to spend time to be able to see all the documents.

Capitol/Supreme Court/LOC are each quite a bit too depending if you want to do tours or just see the outside.

I would try to do some of it the morning of day three if possible
