Hi there First time post can anyone help me with my project please!!

Im trying to build a Led circuit for a model ship in total there is 16 Led's

11 of them have a Vf of 4V @ 20mA
5 of them have a Vf of 2.5 @ 20mA

With a 9V Dc power supply and a switch.

Can anyone tell me how I would go about connecting them in and with what resistors.
