Is it normal to have FUE implants positioned in a row? Will this look natural when the hair grows in? (Photo)

A random pattern is what we aim to achieve to give the most natural appearance.  The angle, density, depth & location of sites are critical and all a part of the expertise necessary in the design of a hairline, temple or even a crown whorl.  A solution if you don't like your result is to do scalp micropigmentation aka SMP (see link below), a revision transplant  (see link below) or wear your hair longer. 

I usually use a random pattern and diamond shape distribution for achievement of natural look . İmplanting the grafts in a row like fashion would not yield a good natural result.
