this special version of telescopic current source looks different than a conventional one.

what's the purpose of (ma5 to ma8) or (ma1 to ma4)?

Dear Shemo:

The purpose of these transistors is biasing the gates of the m5, m6, m3 and m4. The main objective of this configuration is to increase the impedance of the vop and vom nodes.

Greetings.
