Is there any way I can import AICC object? or only Scorm object work? I know SCORM "includes" aicc or is aicc compliant but i've noticed i can only import scorm.

Yes , you can use AICC but note that it doesn`t have SCORM advantages in Docebo LMS ;)

the problem is that I tried importing an AICC object and I got the error that the imfmanifest.xml wasn't found. so maybe the aicc object first has to be "converted" to scorm before loading? or is there a workaround?

If you create your scorm/AICC with "Reload editor" , will not face with any problem ,

I already have a list of AICC courses.....that are from an old elearning that we used. And i wanted to know if those can be uploaded. Is there a way I can convert aicc to scorm using Adobe captivate or other software? So I can then upload them?

Hmmm,
It depends on RELOAD Editor !
If RELOAD Editor can read your AICC files , so they could be restored for Docebo .
