What type of screw driver do I need for this type of small socket 5 sided star screw?
Most likely, tamper-proof TORX Plus.



For this



Or Pentalobe, a mainly Apple thing.



Some places simply call it Star screws/heads. Check for security bit sets. I've gotten some at a dollar store, home depot, lowes, ebay, the usual places.

If you don't care about saving the screw, any common screw extractor set will work.

You could also try the melted bic pen method.
