Antilock, Battery and brake light on and steering stiffened

[Zooey32]

So i bought my first car a couple weeks ago never thought id own a Z especially because I'm still learning how to drive manual . Anyway i drive a 1991 300zx N/A as i was driving to the store my battery light turned on then my anti-lock light and my brake light. my fan isn't moving and my belt either also my steering stiffened up and was hard to turn what may be the problem. I'm a completer noob and oblivious i have very limited to non existent car knowledge any input would help thanks.
