A total of 213 emergency calls were made, with crew attending 133 of them.
The most serious incidents were at Sandy Row and Ravenscroft, where firefighters were required to douse apartments and houses to protect them from the heat and flames.
Assistant Chief Fire Officer Alan Walmsley said: “An appliance was attacked in Belfast at around 1am and then in Larne half-an-hour later.
"No fire-fighters were injured.”
Concerns were also raised by displays on some bonfires, with flags and politicians' election posters burned.
A coffin bearing the image of the late deputy First Minister Martin McGuinness also appeared on one east Belfast bonfire, while a racist slur against Celtic footballer Scott Sinclair featured on another.
The Northern Ireland Office has said it does not operate a bonfire compensation scheme, after windows in an apartment block were broken.
DUP leader Arlene Foster has told UTV she condemns bonfire displays like the coffin bearing a picture of the late Martin McGuinness.
Right across Northern Ireland, tens of thousands of Orangemen and their supporters have been on the march.
