Not sure if your assignment requires weight and cobtact force for he first 2 qns but i put it in anyway. Do note that the 25N you put for the first 2 qns is friction, not weight and should always oppose the motion of the body.
For qns 3 there is acceleration towards the northwesterly direction since there is a net force present (the two 1000N overpowers the two 25N friction)
For qns 4, onit any 0N forces and as usual the 25N friction should oppose the motion, but sonce the object is in freefall, you may onit the friction from any surface (assuming negligible air resistance)
Hope this helps :)

*omit any 0N forces (typo in last paragraph)

Also, for #3, where did you get 35 from?
