Imo, yes

250.148 Continuity and Attachment of Equipment Grounding
Conductors to Boxes. If circuit conductors are spliced within
a box or terminated on equipment within or supported by a
box, all equipment grounding conductor(s) associated with any
of those circuit conductors shall be connected within the box
or to the box with devices suitable for the use in accordance
with 250.8 and 250.148(A) through (E).
Exception: The equipment grounding conductor permitted in
250.146(D) shall not be required to be connected to the other equipment
grounding conductors or to the box.

Yes 250.158 B
Dennis beat me. But I will say that's the way we have always been told to twist them all together. . I thought it was a trade thing. Turns out their is a nice little paragraph in the NEC just for that.

Ok, but can strip the wire long attach to the box and then up to the bundle to wirenut? I am trying to keep my EGC count to five. doing this would eliminate another wire just to ground box.

Agree, yes. Remember that all EGCs only need be counted as a single wire for volume calcs.
