This scenario is complex but easy to handle. There are so many variables to take into consideration, speed, time of arrival, a/c type, airspace, direction of arrival, runway in use, IFR or VFR, can a/c accept visual approaches, weather conditions. Unfortunately experience is the only answer, the controllers decision is final. It is always safe but not always expeditious and orderly. For someone to answer this question with no experience would be difficult. However, some sort of logic being applied, with basic reasoning would help.
I think your answer is fine, however the Jumbo could be first, the medium second, and the 2 light a/c third/fourth. Any of the larger a/c could go visual and not carry out an ILS. The light a/c may go visual and orbit.
Two many variables, not one answer.
