gemz123,
You sent me a PM asking the common name of T. hoehnelii, how big they got, etc. I didn't initially realize what you were looking for (a chameleon that you can hold) and thought it would be beneficial if I mentioned here a couple of the things I said in my PMs.
First, I do not in general consider chameleons as a whole to be "friendly" animals. Some individuals do behave in a friendly manner but I do not consider this to be the typical norm. In my opinion friendly and not aggressive are not the same thing so even non-aggressive individuals would rarely qualify as friendly in my opinion. Most chameleons would prefer to be left alone. Some species in general tolerate not being left alone better than others, and you may be more likely to find a "friendly" individual in one of these species, but most individuals of even these species still want to be left alone for the most part.
Secondly, as a general rule of thumb, I have found that the species which might be considered to have a tendency to be more aggressive (C. calyptratus, F. pardalis, C. dilepis, etc.) typically are so because they are less afraid or shy and are often the hardier species. The species which most would not consider being prone to aggressive behaviors typically are much shier and stress out much easier. Obviously this is a generalization and there are exceptions (ex. T. oweni is often quite aggressive but is said to stress out very easily) but if you are looking for a species you can hold, I would recommend a species that one might consider to be more prone to being aggressive as they are more likely to handle being handled alright.
Bottom line, if you want a chameleon to be able to hold it, get a CB panther or a veiled in my opinion. There is a chance you may end up with a more aggressive animal, but you are less likely to cause the death of the animal because of the handling than you would be with some of these smaller, shier, more delicate species.
