I had a FUE hair transplant a few days ago and some follicles are sticking out. Is this normal?

Properly transplanted hair follicle grafts should stick out about 1 mm.  Grafts that stick out 2-3 mm or more may be poking out of their holes   Grafts that are very much exposed above the level of the skin are said to be "popping". Graft popping occurs for many reasons including tight packing of the grafts with not enough room, bleeding issues during or after the procedure, and excessive moisture with post op washing that causes the grafts to absorb water. Without seeing the scalp and photos, it's not possible to tell what's happening. Grafts often settle in 24 hours and look less exposed above the level of the skin. If you have concerns, it's always great to take a picture and show them to your surgeon or better yet .... meet again in person. 

The hair shaft that is attached to the follicles detaches from the follicle and comes out and eventually falls off.  If the follicle that looks like a bulb is coming out then you are losing that graft.  All the follicles need to be under the skin to survive.  Youcanvisit your doctor to see if its the hair shaft that is sticking out or the follicle.
