VPNs protocols classification in osi model ?

Hello i am confused in vpns protocols and i need little clarification if possible, is it safe to say that 
layer 3 ( network ) vpn protocols : IPsec,MPLS
layer 2 ( data ) vpn protocols : PPTP,L2TP,L2F

layer 4 ( transport ) vpn protocols : SSL/TLS

layer 7 (application ) vpn protocols : SSH


and what about openvpn ?
and it will be great to suggest more vpn protocols for me with their related layer in the osi model.
Thanks in advance.
