MOS ASI ??? and Tabs?

I know you have many ASI on your in your training jacket. My question is for someone who is Ranger Qualified, Airborne (not all rangers are airborne), Air assault, Pathfinder, and Halo Qualified, how many of those qualifications will be listed in his MOS CODE. I.E. >>> 11B3V0 means I am staff sergeant airborne ranger qualified. Also if a person is Special Forces qualified, I am not but attending SFAS soon how many tabs can a person wear on their left shoulder?? I know I will be allowed SF Tab and Ranger and of course the Airborne tab above the patch. I saw someone with JFKSWCS patch wearing the ranger and sapper tab, so I was wondering if he would have to give up one of the tabs.
