How many different triangles exist so that any side-length is less than 4 units long and the sum of all three sides is equal to 5?

Let's ignore 'triangles' with sides of length zero. I assume that you mean triangles with sides of whole-number length; otherwise, the possibilities are infinite.
The sides have to add to five. There are only two ways of doing this:
1 + 1 + 3
1 + 2 + 2
Both of these possibilities satisfy the other constraint mentioned in the question.

How many tessellation does exist?
Infinitely many. Every triangle can tessellate and each will result in a different tessellation. Since there are infinitely many possible triangles, there are infinitely many tessellations.
