No, in third angle orthographic projection the arrow points away from the position where you have to section. For first angle orthographic projection, the arrow always points towards the direction of sectioning.
Yes, It is normally expected from students that they use their own projection angle if it is not stipulated. The product that will be manufactured will come out the same.
The corner in general are neglected in sectional drawing. The purpose of such a section is to get through the centre of the holes. The holes are the places where assembly components will be placed. Please see a similar example on this link. ruclips.net/video/3lGFp-LA0l8/видео.html
