transition elements exhibit more than one oxidation state(possible charge it can hold).this is bcoz they use both ns and (n-1)d orbitals for bonding.the energy difference between ns and (n-1)d orbitals is very less,so both these electrons participate in bonding.
usually,they exhibit +2 oxidation state involving their ns electrons.

This is because when transition metal atoms react woth other atoms, they can lose differeiongnumbers of electrons, depending on what compound they are reacting with. For example when iron (a transition metal) reacts with oxygen it always gives oxygen 3 electrons and becomes Fe 3+. It just depends what substance the transition metal is reacting with.

Transition Metals can have 2 charges beacuse these metals have 2 to three electrons intheir outer shells.

yeah, some have more than 2.
