They were convicted under sections 13 (abetting unlawful activity), section 18 (punishment for conspiracy), section 18 (B) (recruiting for terror act) and section 20 (punishment for being member of terrorist gang or organisation) of the UAPA last week, he added.
The Pakistani LeT members Asgar Ali, Shakkar Ulla and Shahid Iqbal were accused of recruiting persons for various anti-national activities.
The other five accused are Babu alias Nishachand Ali, Hafiz Abdul, Pawan Puri, Arun Jain and Kabil, Jindal said.
Babu and Pawan Puri came into contact with Asgar Ali in Bikaner Jail, he said adding that Kabil came into touch with Shahid Iqbal in a Punjab jail.
All of them were in touch with a LeT commander based in Pakistan through mobile, Jindal said.
The Rajasthan ATS had swung into action on receiving an alert from central intelligence agencies intercepting telephonic conversation between the LeT men lodged in jails and Lashkar commander in Pakistan in 2010.
