Broken tooth, teeth gap, imperfect jaw position. I want a normal teeth set. What should I do. (photos)

I have got a rabbit tooth with lot of gap. I think I also have a milk tooth canine in bottom. There are gaps in my teeth. My front tooth broke when I was a child. I have got a cap that does not make me look good. Is it possible for me to have a normal teeth set again and a good smile. I sometimes feel that my lower jaw is little behind. Please suggest the corrections and is it possible to be normal again.
