DECORATE with WadAuthor

It's possible to modify the DECORATE lump with WadAuthor?
If it is, then how I do it?

I doubt it. WadAuthor is 7 years old and the DECORATE lump has been introduced in 2002.

No.

Its possible to edit the decorate lump in notepad.

You have to edit the decorate lump outside (ie. in notepad) stick it in your wad and then edit the zdoom.wcf file to put the new things in. To do this, copy-paste one of the existing entries, replace the 0x0000 (whatever) number with the new thing's DoomEdNum, the sprite name with the one from the new thing, and the category number you want the thing to be in. (if you have a lot of decorate things, it's best to create your own wcf file)
