These names are taken...And if the people who own the trademarks for these names (or even if they don't but have been using these names commercially before you started and can prove that in a court) sue you for using their names, you'll be in trouble.
I would recommend not to use names that are already taken.
And by the way, bahria name is already there in the education business(I don't know if bahria uni is a bahria town project), but that would be a problem. Same with askari and allied. I know there's allied bank, maybe there's allied something else as well and there may be an allied school too (isn't there already?). So these people will/may come after you to defend their name...
Remember anything is illegal only if it can be proved in court to be illegal. But why take the chance right ?
Come up with your own unique name....
