Hey code here problem below:

names = {"James","John","Johnny","Cesar"} 
subnames = {"Rodriguez","Johnshon","Thomson","Black"} 
  
function nick() 
players = getElementsByType("player") 
setPlayerNametagText(players,math.random(names).."_"..math.random(subnames)) 
end 
  
addCommandHandler("rpnick",nick)

local names = {"James","John","Johnny","Cesar"} 
local subnames = {"Rodriguez","Johnshon","Thomson","Black"} 
  
function nick() 
    local players = getElementsByType("player") 
    local nbrNames = table.getn(names) 
    local nbrSubnames = table.getn(subnames) 
    for i, player in pairs(players) do 
        setPlayerNametagText(player, ""..names[math.random(nbrNames)].."_"..subnames[math.random(nbrSubnames)].."") 
    end 
end 
addCommandHandler("rpnick",nick) 
  

Tested, if you want allow the command only for admin :

  
local names = {"James","John","Johnny","Cesar"} 
local subnames = {"Rodriguez","Johnshon","Thomson","Black"} 
  
function nick(thePlayer) 
    local accountname = getAccountName(getPlayerAccount(thePlayer)) 
    if isObjectInACLGroup("user."..accountname, aclGetGroup("Admin")) then 
        local players = getElementsByType("player") 
        local nbrNames = table.getn(names) 
        local nbrSubnames = table.getn(subnames) 
        for i, player in pairs(players) do 
            setPlayerNametagText(player, ""..names[math.random(nbrNames)].."_"..subnames[math.random(nbrSubnames)].."") 
        end 
    end 
end 
addCommandHandler("rpnick",nick) 
  

Enjoy
