What lizards go in cages?

I am looking to maybe buy a big lizard cage, depending on what type of lizards can go in there. Nothing that gets too big though and how does it feed won't stuff escape from the cage? 5ft tall and 4x4 width and length. That is the size. I know i could put Iguana but they get too big don't they? anything else I could put in there? Sorry I have been asking alot of ?'s here in the reptiles section. Thanks
