The easiest would be to get the schedules and load profile from OpenStudio for example (from the different templates they have).

I'll answer in more detail only for housing (single home and multifamily), so it's a partial answer.

For apartments/housing, the load values and profiles in OpenStudio are derived from (Hendron, 2007), see below.

You could also try to customize it further based on the NREL research on the matter, which expands from several sources including RECS.

The Building America report has some good information for your problem starting page 36, listing a bunch of MELs (miscellaneous Electric loads) with tables of consumption per appliances and average unit/household for approx 100 MELs. The spreadsheet has the same information but allows you to see the hourly profile as well as customize the appliances you do have (In particular on tab Detailed "MEL" you can input in column D the which MELs and how many you know you have. There's also a list of sources in there, including the first one "Bob's judgment" :) )
