we use VRF system for A/c we use value given in LEED guide Rc 2.2 lb/ton
As per the the default calculation we get points but the reviewer tells Rc for VRF is very low it may be "3 - 6" lb/ton
Is it possible to get points for VRF system

The refrigerant charge (Rc) should be the actual amount of refrigerant being used. The table in the Reference Guide shows you the maximum charge that would still meet the credit - it is not a default.
In the case of VRF (or any split system), you must include all the refrigerant in the distribution piping. This usually makes the credit very difficult for VRF systems to achieve.
