In order for a VLAN interface to be up, the VLAN needs to be configured on a access port (Directly connected hosts) or the VLAN needs to be allowed over a trunk. Mind you that the interface or trunk need to be up for the VLAN interfaces to come up
You can configure access ports assigned to those VLAN's and use the command no keepalive command to bring those ports up, without having something actually connected to the physical port
