Then I'm failing to see what the problem is. You have 7 entrances; therefore at least 5 must be accessible (if you provide only 4, then that is 57%, which is less than 60%). Once someone is inside, you have one elevator for the accessible route to the basement and the 2nd story. For means of egress, you'll need at least two egress paths from the 2nd story and the basement, which can be enclosed exit stairs that discharge at grade level. The two exit stairways can also be considered as the two required accessible means of egress if they comply with IBC Section 1009.3; or, you can make one stairway comply with IBC Section 1009.3 and make the elevator your second required accessible means of egress, provided it complies with IBC Section 1009.4.
Maybe if you post some floor plans we can be more specific about our comments.
