I hope your attachment very small size. Instead of attach please post all the details as per Orafaq rules.

Also please try to avoid duplicate post.

Thanks

Move or drop the objects that are beyond the size you want.

Why do you want to shrink SYSTEM tablespace?
Every bit of space in it is in used (unless you created you own objects in it).

No as I can't download files.

Check DBA_EXTENTS to know what is at the end of the files.
Or use a script I posted at:

You can't if they are SYS objects (but indexes).

try this command
alter database datafile '<system datafile file path>' resize 6G;

As your current SYSTEM datafile is 5.37Gb give it as 6G when resizing.

please try this on test DB and then apply it in production

OP's purpose is to DECREASE size not to increase it.
And OP knows your command as it posted it.

Please read the topic before posting.

create a new tablespace e.g. system1 and move all the objects to the new tablespace and then resize the system tablesapce.

No, you don't move any object from SYSTEM tablespace out of it (unless you badly put in it some user objects).
Objects in SYSTEM tablespace are owned by Oracle, you don't do anything with them unless you are an expert or you have the go from Oracle support.

I would strongly suggest against doing this, for anything other than user created objects.
