Looking at Table 39 for causalities. A human standing represents about 8-10 square feet. At 10 feet he could expect to be hit by .234 x 10 = 2.3 fragments.

Entrenched is just head above parapet. Wearing a helmet would give protection of about x .75
If you are using four 15mm figures on a stand, assume about a 25 meter frontage. With a grenade landing in the middle of a team deployed in a skirmish line the two middle figures would be about 3-4 meters from the blast. The outer ones would be 10-12 meters from the blast. It looks like the inner two would be hit by an average of 2 fragments and the outer ones about a 50% chance to be hit by 1 fragment.
