Actually there are over 120 different kinds of HPV. Most kinds of HPV are harmless and do nothing, but some kinds of HPV can cause cancer and warts.
About a dozen HPV types (including types 16, 18, 31 and 45) are called "high-risk" types because they can lead to cervical cancer, as well as anal cancer, vulvar cancer, head and neck cancers, and penile cancer.
HPV types 6 and 11 can cause a rare condition known as recurrent respiratory papillomatosis, in which warts form on the larynx or other areas of the respiratory tract.
HPV types 1, 2, 3, 4, 6, 7, 10, 11, 13, 16, 18, 31, 32, 33, 35, 39, 42, 43, 44, 45, 51, and 55, as well as more kinds, are responsible for warts common warts, planter warts, flat warts and genital warts. The most common kinds of HPV that cause genital warts are kinds 6 and 11 which make up about 90% of genital wart cases.

HPV types are number in the sequence they were found.
The HPV family has at least 83 well-documented genotypes. Some believe that the number of HPV types has already approached 130 or more.
Multiple clinical associations with unique genotypes of HPV have been documented. HPV types and their association with the clinical disease are as follows:
Plantar warts - 1, 2, 4, 60, and 63
Common warts - 1, 2, 4, 26, 27, 29, 57, 65, and 75-78
Meat/poultry/fish handlers - 1-4, 7, 10, and 28

Squamous cell carcinoma or actinic keratosis - 14, 16, 18, 36, and 41
Squamous cell carcinoma, keratoacanthoma type - 7, 9, 16, 29, and 37
Squamous cell carcinoma, in immunocompromised - 48 and 60
