|is it possible for me to configure vlans on such network...|
Sorry but no, it's not possible.
You could have a VLAN, or VLAN's on the one managed switch that is VLAN capable. But, without a router (or a Layer 3 switch capabale of routing) your VLAN's cannot go out beyond the single switch or communicate with each other.
Even with a router, you're stuck with VLAN'ing on the one switch only since the others are unamanged.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
