In regards to the name Sant Samajh I see no harm in this name it would be like having
an organization called Khalsa Samajh or GUrmukh Samajh . THe word Sant, Khalsa, and
Gurmukh all mean the same thing.
In regards to calling a Gurmukh sant there is no harm in this as well. Guru Sahib refers
to Bhagat Prahlaad as Sant, and in rehatnamey BHai Nand Lal says not to cause any harm to
a "Sikh Sant". Also, In his book Ranglee Sajan , BHai
Randhir SIngh Ji refer to some Gurmukhs as Sant.
