Of your list, the chicken legs will take the longest. Is the bone in the chicken breast? If yes, that will take a while also.

Also, monitor your heat. This is very important. It's not just time on the grill, you have to know how hot it is.

If I was cooking your list, chicken legs first, then breast, then chops, then burgers and steak.

Honestly, your list seems kind of large. I would do a lot of that in the oven or in a cast iron, then finish it on the grill, especially the chicken legs/breast. Doing chicken breast well requires a lot of practice and knowing how hot your oven is or a meat thermometer.
