Hi,
>> those icon can be deleted
Maybe I misunderstand something? You can't select the icon and you can't delete them. It's not a constraint showing up in your screenshot (or I don't see what you mean, I see a lot of yellow question marks).
ANNOMONITOR is just a variable to show or to not show the warnings, they are not deleted or the issue is not repaired by just turning them off.
That's what I mean:

>> one more question Project units in autocad is the same as ddunits set-up?
"Project" is a word that has to used carefully for AutoCAD, AutoCAD itself does not know a project like AutoCAD Architecture or other verticals.
Within the drawing I suggest to use command -DWGUNITS and set it to the unit type you are drawing your parts.
