Can someone explain what the numbers represent on the legend as highlighted?
For example, on the line side it says 6-2/0.
Is this a range from 6 AWG to 2/0?
On the ground bus it says 14-6, is this a range from 6 AWG to 14 AWG or 6, 14 guage wires?

so if there is a range from 6-14 for conductor size, is there a "maximum" number of conductors allowed under a terminal?

That triple tap is not legal and neither is that GEC. The armor should be removed and the cable should be terminated with an approved connector.

One conductor per terminal.

Anyone else notice the aluminum and coper wires in direct contact under that clamp?

Great thanks. Last question; so if the legend says #6-14, then per NEC you are only allowed one (1) conductor per terminal so either a 6,8, 12, or 14 (co) is allowed in that terminal, yes?

That is correct.
Some panels allow 2 conductors, but only on the ground bar.
That will be listed on the legend also with the other info you have found.
