Newbie question

Just joined my 1st group in 1st dungeon and I did not see my groups names displayed? how do I turn that on?

ESC > Interface > Names
will bring you to the name display options

I have tried that, no mention of groups at all, I have selected pretty much all of the options and still no stacked indication of group health or status

The only other thing I could suggest short of a complete UI reset would be to try playing with the V, Shift-V, and CNTRL-V toggles.

Are you using any UI mods? If so, which ones? Some of those will affect how groups are shown. (And could potentially hide them altogether depending on settings.)

Are you talking about the party frames? Rather than individual name plates?

If so, there are options in the groups and frames sections which can turn things on and off. You may also when in a group see a sort of label thing sticking out from the left hand side of your screen. Clicking on that will bring out a box with some options for party frames
