4. Lakshadweep

5. Delhi (National Capital Territory of Delhi)

6. Puducherry (Pondicherry)

These Union Territories have varying degrees of autonomy and are governed by administrators appointed by the President of India, who is the head of state. It is important to note that the number of Union Territories in India may change in the future as per government decisions.
