Because your second and third condition can be merged, you can use ismember:
data={'Pass','Pass{overflow :1,unbound:5,warning:9}','Miss';
'Pass','Miss','Trigger';
'Passs','Pass','Pass'};
L=ismember(data,{'Pass'});
output=2*ones(size(data));
output(L)=1;
Note that this requires exact matches. You could also write a custom function and use cellfun:
output2=cellfun(@my_custom_fun,data)
function val=my_custom_fun(str)
if strcmpi(str,'pass')
val=1;
elseif strcmpi(str,'miss')
val=2;
elseif contains(str,'Pass')
val=1.5;
else
val=2;
end
end

@Mekala balaji: did you copy the function that Rik gave you, and save it to your Search Path (e.g. the current directory) using that function name?
