How can I make a function run on multiple objects simultaneously when it contains a loop?

I have a script that has been troubling me for some time. Whenever NPCs spawn, they're supposed to get a checkpoint and move to that position. However, my script uses pathfinding. If it were simply a matter of using the MoveTo function once, it would be no problem. Here is my script:

wait(1)
npcs = game.Workspace.ActiveNPCs:GetChildren()
checkpoints = {Vector3.new(-99.2998886, 30.2999496, -91.5046234),
Vector3.new(-22.3003178, 30.2999496, -100.502426),
Vector3.new(47.6997795, 30.2999496, -100.501404),
Vector3.new(-18.2993164, 30.2999496, -48.5024147),
Vector3.new(-17.2979679, 30.3000755, 41.4907074),
Vector3.new(59.7020416, 30.3003025, 107.491859),
Vector3.new(60.7024612, 30.299818, 35.4920883),
Vector3.new(59.7007599, 30.2999249, -33.5009384),
Vector3.new(-19.2975655, 30.2995892, 115.490532),
Vector3.new(-118.297119, 30.2998695, 111.488739),
Vector3.new(-104.297592, 30.3003025, 29.4886169),
Vector3.new(-111.298828, 30.2999249, -19.5043755),
}

--[[local ray = Ray.new(nonPlayerChar.Torso.Position, nonPlayerChar.Torso.CFrame.lookVector*2)
local hit, position = game.Workspace:FindPartOnRay(ray, nonPlayerChar)
local distance1 = (position - nonPlayerChar.Torso.Position).magnitude--]]

wait(1)
function moveNPCs(v)
    local checkpoint = checkpoints[math.random(1, #checkpoints)]
    print(v.Name .. " will move to " .. tostring(checkpoint))
    local path = game:GetService("PathfindingService"):ComputeRawPathAsync(v.Torso.Position, checkpoint, 100)
    print(path.Status)
    local points = path:GetPointCoordinates()
    for _, point in pairs(points) do
        v.Humanoid:MoveTo(point)
        repeat
            local distance = (point - v.Torso.Position).magnitude
            if v.Humanoid.Sit == true then
                v.Humanoid.Jump = true
            end
            if point.Y >= v.Torso.Position.Y + 1.5 then
                v.Humanoid.Jump = true
            end
            local ray = Ray.new(v.Torso.Position, v.Torso.CFrame.lookVector*2)
            local hit, position = game.Workspace:FindPartOnRay(ray, v)
            local distance1 = (position - v.Torso.Position).magnitude
            if hit ~= nil then
                v.Humanoid.Jump = true
            end
        print(v.Name)
        wait()
        until distance < 3
    end
    wait()
    print("test")
end

game.Workspace.ActiveNPCs.ChildAdded:connect(moveNPCs)

for _, npc in pairs(npcs) do
    moveNPCs(npc)
end

The event causes each NPC to move at the same time, but their movements do not seem correct. The generic for loop generates the desired result from individual NPCs, however the NPCs do not move simultaneously. What can I do to make the function run on all NPCs at the same time, or at least make them move at the same time? Please, shed some light on me! Thanks in advance.
