I'm using the tikzpeople package to draw some scenarios. Now I would like to give the hat, that the builder is wearing to alice, charlie, and dave. As it is not attribute like the monitor or the shield I don't know how to do that.

(I've built the example with inkscape.)

You could misuse one of the (unused) accessories:

documentclassarticle
usepackagetikzpeople
begindocument
begintikzpicture
makeatletter 
tikzpeople@builder@definecolors
lettikzpeople@person@paintshieldtikzpeople@builder@painthat
node[alice,shield,minimum size=1.5cm] at (0,0) ;
endtikzpicture
enddocument

Ok, I managed it by taking a closer look into the files of the tikzpeople package.

To define a new combination (builderalice in my case) you need to define a new file tikzpeople.shape.builderalice.sty where you combine the parts and the according colors. Then you need to call tikzpeople@declareshapebuilderalice (as it is intended to not be called from outside and contains an @ you need to wrap it in makeatletter and makeatother).

documentclass[tikz]standalone
usepackagetikz
usepackagetikzpeople
usepackagefilecontents

beginfilecontentstikzpeople.shape.builderalice.sty

endfilecontents

makeatletter
tikzpeople@declareshapebuilderalice
makeatother

begindocument
begintikzpicture[]
 node[builder,minimum size=1.5cm] (T) at (-1,0) ;
 node[alice,minimum size=1.5cm] (N) at (1,0) ;
 node[builderalice,minimum size=1.5cm] (A) at (3,0) ;
endtikzpicture
enddocument

This seems to be an XY question. What you might be really looking for is the TikZlings package in which you can add the accessories at will.

documentclass[tikz,border=1mm]standalone
usepackagetikzlings
begindocument
begintikzpicture
 owl
 thing[tophat,scale=1.5,yshift=-0.6cm,xshift=-0.05cm]
 beginscope[xshift=2cm]
 bear[magichat=violet,
 magicstars=yellow!80!brown]
 endscope 
endtikzpicture
enddocument
