Yeping, not sure the question was addressed to me, but per the Pymol Align
wiki page the numbers you are referring to are
1. RMSD after refinement
2. Number of aligned atoms after refinement
3. Number of refinement cycles
4. RMSD before refinement
5. Number of aligned atoms before refinement
6. Raw alignment score
7. Number of residues aligned
