Hello,
I have a string with multiple substrings. Each of the substrings is a pathname. How can I use importdata or textscan to import these substrings in seperate tables?

You have those strings in a text file? Why don't you show the sample of text file?

I tried this
[FileName,PathName] = uigetfile('../*.txt','MultiSelect','on','choose','the path');
numfiles = length(FileName); c = char (FileName);
string2=strcat(PathName,c);
for ii = 1:numfiles;
% it work until here
a{ii} = importdata(string2);
end

Try this:
[FileName,PathName] = uigetfile('../*.txt','MultiSelect','on','choose','the path');
numfiles = length(FileName);
a = cell(numfiles,1) ;
for ii = 1:numfiles
c = char (FileName{ii});
string2=strcat(PathName,c);
a{ii} = importdata(string2);
end

uigetfile does not return strings, it returns a cell array of char vectors. Iterating over a cell array is easy, so just do that. Also use fullfile rather than concatenating strings using strcat (or anything else).
[fnm,pnm] = uigetfile('../*.txt','MultiSelect','on','choose','the path');
C = cell(1,numel(fnm));
for k = 1:numel(fnm)
C{K} = importdata(fullfile(pnm,fnm{k}));
end

Is it possible that I get this as result? I have to say that the file I want to import is rather complicated. It has headerlines and variable names. Sorry if I wasn't clear.

"Is it possible that I get this as result?"
Of course it is possible. Read the importdata help to know what it returns: the structure and its fieldnames are clearly explained there. Note that you could easily convert the cell array of scalar structures to a more convenient non-scalar structure:
S = [C{:}];
S(1).data
S(1).colheaders
...
S(2).data
...
