hi this is tysonchat i have a question ive finished the 3rd person guide u wanted to know how to import downloaded 3d models

If I understand your question, you want to import 3d models? As long as they are in a proper format like .obj or .fbx you can just click the import button and select your file. Otherwise you need to use a program like 3ds or Maya to save the model as .obj or .fbx.
