Could you identify the saintly figures in this painting?

I can see Moshe with the tablets to the left, and next to him is someone with a knife and tablet, then there is Peter, a dsiciple, and to the far left someone with ablade, and someone next to him. Above him is an messenger with The Pillar Of The Flagellation and a palm branch. Below that are messengers with a stick like the ones used to read scripture and another stick. below that we see the sme thing and a huge sphere. On the right we see multiple figures with scepters. Now if you clikc "newer" you see the space below and in the hallway behind, you see a cross on the ceiling in an unknown scene. what's that?
