Okay, here are some more changes:
The halftrack Sd.Kfz.250 was the little brother of the Sd.Kfz.251 mentioned above. It was not built by Hanomag, but by DEMAG of Duisburg.
While searching if DEMAG should be written in capital letters or not, I found out the exact meaning of the name:
DEMAG = Deutsche Maschinenbau-Aktiengesellschaft (German Engineering Corporation). We also write FAMO and most DEMAG vehicles in capital letters, so the first step will be renaming all "Demag" vehicles to "DEMAG".

Looking at the Hanomag company, their name is similar, meaning "Engineering Corporation of Hannover" in English. Therefore, it might be the best to change all "Hanomag" to "HANOMAG", since I couldn't find any HANOMAG writing with small letters anywhere.

But now, here are some changes for the Sd.Kfz.250 and Sd.Kfz.10/11:
1) Both halftracks share the same chassis, so the model name is known. Nearly all of them are listed as either "Typ D 7" or "Typ D 7 p". I suggest to drop the "Typ" in the model name, since mostly only online model car shops use it, but no pages related to military vehicles.
The right name for the vehicles in the following links would be "Typ D 7" or "Typ D 7 p":

2) Like all German military vehicles, they built a lot of different versions, some of them are just different in details. In order to avoid confusion, I will first only list the different versions of the Sd.Kfz.250, while the Sd.Kfz.10 will be done in another post.
To make it as complete as possible, I'll post every info field that needs to be changed for the different groups of vehicles (I don't include the Demag/DEMAG change if the model name is already okay)
Before that, this is how a changed page looks like:
