Hello Teymur,
you are configuring stateful NAT SNAT in HSRP mode.
the feature provides a one to one corrispondence between an HSRP group/instance and SNAT instance, so you should use a different mapping-id for SNAT2 redundancy group.
otherwise if what you want is to have two set of stateful NAT rules associated to a single HSRP group you should merge the NAT rules.
if you want to split the NAT rules and to associate them to two different HSRP groups, each group should use a different redundancy name and a different mapping id
see
and

for ip nat stateful id
Hope to help

Did you ever find a solution for this ? I have the same issue ...
The problem is not the repeating mapping-id because the error happens before that command is entered, when you try to put a second redundancy.
And trying to configure a second snat group
ip nat Stateful id 2
doesn't work for me either:
% SNAT with id : 1 already running. Please remove and reconfigure%
