What do you think of those rivets
After I am done riveting two parts using the pneumatic squeezer I noticed that some of the rivets manufacture heads are a little bit bent and their bottoms are not flush with parts. I found out that was because the work was not clamped tightly and the squeezer flex moved the two parts so I fixed for the remaining rivers.
Do you think I should drill out those rivets although the shop heads look good?

You should drill them out. Shop head should be flush to part.

Definitely unacceptable. Suggest you get some practice riveting before going further

Apply moderate pressure on the manufactured head with the rivet gun, and just enough pressure with the bucking bar to hold it against the rivet. Let the mass of the bucking bar do the work

Practice
Practice holdi g pressure against the factory side and keeping the yoke perpendicular to the surface so the ram is perfectly aligned with the shank.
You'll get it.

Yes, practice, practice, practice. Learn to feather the ram to any position, the pneumatic riveter is heavy but still needs a delicate touch for the initial rivet setting. Good alignment, good seating of the rivet before starting, and slowly advance the ram until your skills allow fast setting.
Quickly pulling the trigger can upset the balance and give unsatisfactory results, until you are more skilled. Be steady.

I suggest doing as Brad said, snug them up a touch with a rivet gun. Drilling them out is an option that I'd save for rivets that really can't be rescued.

I agree and will add a suggestion that when ever possible, position/orient the squeezer so that the rivet set in the movable plunger is acting to form the shop head and the fixed rivet set in the yoke is against the rivet manufactured head.
And even though I am very cautious when recommending builders (particularly new inexperienced ones) remove rivets, the ones with gaps under the manufactured head should be replaced.
