Disproportionation Reactions of the Halogens: Writing balanced net ionic equations for four reactions. See details
(answer to original question)

No, you are not on the right track. 

If bromate is a starting material, it should not appear as a product in reaction 1. Instead, consider how bromide and bromate can react with each other.

If iodate is a starting material, it should not appear as a product in reaction 2. Instead, consider how iodide and iodate can react with each other.

For reactions 3 and 4, a hint would be "disproportionation".
