Nope Tetra is 4. A tetralogy is a compound work that is made up of four (numerical prefix tetra -) distinct works.

The 20th Century Fox marketing team coined the synonym "quadrilogy" for the release of their Alien DVD box set The Alien Quadrilogy. This uses the Latin numerical prefix quadri-/quadr- instead of the usual Greek Tetra-.

For 5 related pieces of work - Pentalogy.
A pentalogy has also been called a "quintology", basing the prefix on Latin quinque - instead of Greek. The musical term "quintet" has also been used.

For 6 related pieces of work - Hexology

For 7 related pieces of work - Heptalogy.
