Can I sing well enough to audition?

I really don't want to make a fool of myself if I were to audition for the talent show, x factor, etc. So I would like some opinions and suggestions of what I can do to improve my singing.

Also could you please critique them individually, if you have the time.

**THESE covers were done last year and two years ago. I can't update because I don't have my iphone anymore. T_T
