The answer is quite simple;
  1. Import data: D=xlsread('data.xlsx');
  2. Sort out the data w.r.t the conditions using logical indexing e.g.:
Lat = D(:,1);
Lon = D(:,2);
DN = D(:,3);
DE=D(:,4);
HD=D(:,5);
DD=D(:, 6);
Index =Lon>= 102.7 & Lon<=105.2 & Lat>=30.6 & Lat<=32.2;
DNnew=DN(Index);
DEnew = DE(Index);
etc.. etc.

again use the indexing option around corner boundaries with <= and >=
