Tamil, Telugu, Kannada, and Malayalam are all dravidian languages. These four are the major dravidian languages spoken today followed by minor languages such as Tulu, Kolami, Kurukh, Malto, Gondi, Brahuvi, Thodai, Kodagu, Irulai, Kurumba,..etc . These four has recognition as state level official languages from the central govt among the total 22 languages.
Telugu is the largest spoken language among the four with 8.3 crore native speakers within India. Tamil has the oldest history among the four with brahmi stone inscriptions dating back to 2nd century BCE, and literature such as Pathupattu, Tolkappiam, Thirukural, Silapathikaram, and manimekalai which all dates to between 1st century CE to 4th century CE. Malayalam is the newest existing among the four. Malayalam was formed from spitting itself up from middle Tamil around 9th to 12th century CE. Malayalis formed their own distinct identity to resist against Chola imperialism and expansion in the 11th and 12th centuries, as our ancestors were loyal towards Cheras who were the traditional rulers of western tamilikam ( present day Kerala).
Tamil, kannada, Malayalam, and Tulu are south dravidian languages. Tamil and kannada split off 3000 years ago from an ancestor language ( which linguists term proto-Tamil-kannada). Tulu is the oldest spoken south dravidian language. Tulu split off from south dravidian much earlier than Tamil and Kannada. When I say “oldest spoken language" don't confuse as “oldest language with history"; both are two different things.
Telugu and Gondi are south-central dravidian languages. Kolami is a central dravidian language spoken by a tribal group in Maharashtra and Madhya Pradesh. Kurukh is a north dravidian language spoken by kurukh tribes of West Bengal and Jharkhand. Brahui is a north dravidian language spoken in Balochistan province of Pakistan.
