Debelyn had 20 - 2 = <<20-2=18>>18 dolls left after giving out 2 dolls to Christel.
Christel had 24 + 2 = <<24+2=26>>26 dolls after receiving 2 dolls from Debelyn.
Christel had 24 - 5 = <<24-5=19>>19 dolls after giving Andrena 5 dolls.
So, Andrena has 19 +2 = <<19+2=21>>21 dolls now.
Therefore, Andrena has 21 - 18 = <<21-18=3>>3 more dolls than Debelyn.
