Normal if u consider him/her a average/normal user... (I don't see any out of ordinary process there)
u can try reduce the auto updater first.....
go to option of the each program (java, google, divX, malwarebytes, etc...) and set the auto update to manual....
u can also disable some not important service/process (apple apps, auto backup, indexing/searching, etc..)
but this need to know what apps/service he frequent use and what he not....
