Parenting meshes?

I am struggling to get meshes to be parented together. my imported FBX consists of numerous individual meshes, and even though in the hierarchy they appear to be parented they are not, so it isn’t quite as intuitive as I am accustomed to in other applications.
what is the process for this? just having a difficult time figuring this out because my model loads up in the wrong worldspace, and i just want to move the main part of the object and have everything else move along with it.

I am very new to UE! it is exciting stuff but operates very differently from what I am accustomed to.
thanks very much,
