Make sure each letter in your {h,e,l,l,o} is a string, i.e., that it is actually

{"h", "e", "l", "l", "o"}

Then use StringJoin:

In[1]:== StringJoin[{"h", "e", "l", "l", "o"}]

Out[1]== "hello"

Do the same for {"This", " ", "is", " ", "a", " ", "test", " ", "message"}, but remember to type the spaces between each word.

In[2]:== StringJoin[{"This", " ", "is", " ", "a", " ", "test", " ",
  "message"}]

Out[2]== "This is a test message"
