Multiple hair per follicles?

It may be normal to see two or three hairs for each incision site as hair grafts may contain 1 to 3 hairs.  If this is not the case and you are concerned it is best to contact your doctor.  Front hair line should have single hairs.

That's normal. Grafts can have anywhere up to 4 hairs each- generally single grafts are placed on the edge of the hairline and 2s 3s and 4s go more inside. This makes the transition towards your natural, thicker hair more smooth and (hopefully) prevents it from looking like you had the transplant.

you may see multipl hair in one "hole" , important point is where do you see it...During the placement of follicular units there will be a
mixture of single, double and a few triple grafts, which help to create the soft
look of a natural hairline.

For the first few lines always go for single grafts,
later doubles Triples and others.So that a smooth transition will be there
giving undetectable hair transplants.

I will assume that you had follicular unit transplants which means that the follicular unit contains between 1-4 hairs each and good surgeons can harvest these units as they appear, 

Follicular units are natural groupings of follicles with 1-4 hairs. With FUE or FUT, follicular units will have 1-4 hairs, so it is not unnatural to see multiple hairs coming from one recipient site as we try to maintain the integrity of a follicular unit. What is unnatural depends on where the multiple hair units are placed. If they are in the frontal hairline that could lead to an unnatural appearance. Hope this helps.
