The GeForce 410M is a really weak GPU with a small amount of Shading Units, low clock frequencies and a cheap and tight memory bus, leading to low Memory Bandwidth. If I remember correctly, it's an integrated GPU but with dedicated memory.
It's going to be tough running some games out there but I think you can the games you mentioned in the lowest settings. NFS might be the hardest to run. Skyrim V offers great graphical customization so you'll be fine on that one.
Your CPU is also not very powerful but it won't be the problem. The weakest component is the GPU.
As for the RAM, without the RAM upgrade, it might be impossible to run those games decently, so you should upgrade the RAM ASAP to 4GB. No more is needed.
