I pasted your example into the attached text file. This reads that file and then parses the number and char array components.
% Read in the text file
ca = strtrim(strsplit(fileread('myTextFile.txt'),'\n'))';
% parse the leading numbers and then the rest after the first space
nums = str2double(regexp(ca,'^\d+ ','match','once'));
chars = cellfun(@(c,x)c(x+1:end),ca,regexp(ca,'^\d+ ','end'),'UniformOutput',false);
Result
nums =
11455
1223
1345
14090
1585
1644
178
chars =
7×1 cell array
{'01adsd@#$' }
{'AaFg3434' }
{'01ADAS FE' }
{'01aFAF' }
{'!%^r^&&*^' }
{'01!ggjGIJiu' }
{'!Aa8Y348Y23RHF'}
