The stronger the bond, the greater the repulsion strength. For example, a triple bond has greater repulsion strength than a double than a single bond.

I think Lone pair Lone pair bonding is the strongest. Then it is long pair bonding pair. And the weakest is bonding pair bonding pair.

The strengths of the repulsions are as follows:
lone pair-lone pair > lone pair-atom > atom-atom
Also, keep in mind that the lowest energy is achieved when the lone pairs are as far from each other as possible, and this is where the length of the bond angles come into play.

Lone pair bonding has the greatest electrons repulsion. That is why we take into account the lone pairs, but we do not take into consideration the number of bonds when determining VSPER shape.

What is the steric number and why is it important?

Tetrahedral has the VSEPR formula AX4 (no lone pairs, four bonds).
Square planar has the VSEPR formula AX4E2 (two lone pairs, four bonds).

To answer your question the steric number is the number of atoms bonded to a central plus the number of lone pairs on that atom. It’s used to help determine molecular shape using VSEPR
