I want to know how much byte I can add in packet or say custom data.

The SDK/protocol will split up the payload in several packets if necessary. A Mesh message is a modified BLE advertisement packet, which is 31 bytes. The payload is something like 11 bytes (don't remember exactly). It is the TrasportPDU field (max 128 bits = 16 bytes). Some of this is used for headers, which leaves you with 10 or 11 bytes.
