Nope Indra didn't fight against the Sirzechs and others but  the second guy who replied to you is completely wrong. Indra is above Sirzechs and by far as it was stated that it would take all the current Satans in term of power to compete with him. So basically it means having (in term of power) at level above Super Devils (Sirzechs and Ajuka) and 2 maou (Serafall and Fallbium) combined.
