Please explain why phenyl cation is not stable by resonance?? Since resonance structures are possible

First to confirm, you mean a benzyl carbocation which is a 'phenyl group' with a carbocation on the benezene's methyl substituent? If yes, it is indeed a stable carbocation due to having a total of 4 resonance structures

How to compare between the deactivators

What specifically is your question?
if it's meta deactivating then why isn't it in the meta position? I don't get it

mina pasha yup cause it has a lone pair which will be donated during activation

Since NH3 as a substituent has a positive charge, it is an electron withdrawing group EWG and makes the ring less likely to want to adopt a positive sigma complex. This makes it a deactivator
