The inside latch for the hood is there another way of opening it?

You have not told me the year, make, model, or mileage of the vehicle you are driving, but here is a generic answer.
Since the early 1980's, cars & some trucks in the U.S. have had a hood release cable actuated from inside the car and attached to the hood latch.
(Bonnets are hats babies wear on their heads).
The wire inside the cable can break, or rust, or stick, as can the hood latch itself.
Hood latches are also somewhat adjustable.
You will need to have a mechanic open your hood from inside the fender, or from inside the bottom of the grille, so you can either replace the cable or lubricate it or the hood latch.
God bless your efforts.

Have someone press down on the hood with their palms while you try and release it, if it does open lube the hood latch with white lithium grease AKA "Lubriplate".

What you can try is to have someone inside of the car pulling on the latch release while you push the hood up and down. Sometimes this will cause the latch to release..

check that the cable is still attached to the latch lever... if not use pliers to pull the cable... sometimes the latch gets stuck... have someone push down on the hood while you pull the latch.

Re;Cant open the hood with the latch inside....
Does the hood release handle have 'resistance' when you attempt to open the hood ??

is it attached to the hood latch on the inside of the van if so it may be the latch under the hood if its not attched on the inside attach it to the hood latch puller

Have one person pull on the latch inside and the other person pull up on the hood (sometimes depending may have to use a thin screwdriver to pry up carefully not to chip the paint). Once open lube the hood latch under the hood with wd-40. Make sure the latch inside is still connected to the wire.

try a crow bar
