Can you use newline seperately or do you always have to use it in fprintf in order to make it work. Theese are my attempts with newline:
this did not work:

This gave a strange result

Is this the only way to make a newline?:

Here is my script for the last line:
rows=3;
columns=5;
for i=1:rows
for j=1:columns
fprintf('*')
end
fprintf('\n')
end

I think you got the answer you need from Wayne, but for future reference, you posted three copies of the same image in this question.

Hi, '\n' by itself outside of special calls is just interpreted as the string (character array) \n
It's not just in fprintf(), sprintf() also interprets escape characters correctly like \n or \t
but yes you're right:
disp('Hi \n nice to meet you')
% produces Hi \n nice to meet you
but
fprintf('Hi \n nice to meet you')
% Hi
% nice to meet you>>

disp(sprintf('Hi \n nice to meet you'))

Hi;
You could simply put { disp(' '); } between two disp for obtaining an empty line.
disp('Hi'); disp(' '); disp('nice to meet you')

Ran in:
If you're using release R2016b or later you can use the newline function, perhaps in conjunction with a string array.
s = "apple" + newline + "banana"
s =
"apple banana"
c = ['apple', newline, 'banana']
c =
'apple banana'

If you want to use newline in verisons below 2016b you can use following comment.
string2Print=sprintf('%s\n','Hi','nice to meet you')

@Vishal
That is what @Saul Stokar suggested two years ago.

supose you want to disp the word 'Ball'. Try
a=['Ball',char(13),'to a new line']
disp(a)

Or
disp("Ball" + newline + "to a new line");

char(10) worked for me, but great advice.

Youj can do it using sprintf :
string2Print=sprintf('%s\n','Hi','nice to meet you');
disp(string2Print)
This prints:
Hi
nice to meet you

Note that you can avoid the extra newline after the last printout as well:
disp(sprintf('%s\n%s\n%s','first line','second line','third line')) prints
first line
second line
third line
(without a newline after the last line printed)
while disp(sprintf('%s\n','first line','second line','third line')) prints
first line
second line
third line
(with a newline after the last line printed)

... unless you are using LiveScript or MATLAB Online or MATLAB Answers. All three of those automatically add the "missing" newline after the last output display on each logical line of code (logical line is physical line except taking into account ... line continuation).
