HELP moles on neck - is this cancerous ?

Sorry for the bad quality it’s quite a hard angle to get so I had to crop most of the pic, but

Okay so sorry about the hair it’s sorta on the back of my neck so it’s all excess from the back of my head , but I’ve literally got this mole (first pic) that I’ve had for as long as i can remember , but in the second pic THERES TWO MORE that I knew nothing about...

I’m just curious to know if they look NORMAL or if I should get them checked out.. I’ve read up of ones about cancer and I’m just really nervous
