  I am writing a master thesis where I am describing how I aligned
protein sequence with template sequence. I use Modellers Saling's
align2d protocol. How should I described /gap_penalties_1d/ and
/gap_penalties_2d/ and what is the difference between them.

See the reference cited in the manual for this protocol, Madhusudhan et 
al, 2006 (PEDS 19, p129):

Executive summary: 1D gap penalties are the regular affine gap opening 
and extension from regular dynamic programming; 2D gap penalties are the 
additional terms used to add structural information to the alignment 
process - e.g. to penalize gaps in regions of known secondary structure 
or in core regions.
