I don't know much about eePanels, and I haven't tested this myself so your mileage may vary. But try the following code:

function eePanels2:RaidPanelVisibility()
	for i = 3, 6 do
		getglobal("eePanel1"..i):Hide();
	end
	local limit = GetNumPartyMembers() + 2;
	for i = 3, limit do
		getglobal("eePanel1"..i):Show();
	end
end
eePanels2:RegisterEvent("PLAYER_ENTERING_WORLD")
eePanels2:RegisterEvent("PARTY_MEMBERS_CHANGED")
eePanels2:RegisterEvent("RAID_ROSTER_UPDATE")

eePanels2:SetScript("OnEvent",function()
	eePanels2:RaidPanelVisibility();
end);
