Is this 4x a week so like M, Tu, Th, F?
You should not be working iron cross if you're not far along with back lever, front lever, and planche. Unless you want to give yourself an elbow or shoulder injury that is.
If you have access to weights you should be doing squats and deadlifts for your leg exercises. No need to get fancy with lunges, box jumps, RDLs, etc. Just do squats and deadlifts.
L-sits and ab wheel are fine.
Rest of the upper body work is likely fine.
