Title: topology

Is it possible to work properly if the intrerswitch ports are configured as trunks, tagged vlan's members with stp enabled?

Yes, however I would be careful to note that straight STP is not a VLANs best friend.  Vanilla STP will fail to differentiate between VLANs and will ignore them in it's tree. MSTP is the correct pick if your equipment supports it.

Also, I would run your uplinks to two equidistant switches in your topology, not 2 to the centre of your ring, this concentrates your failure points unesccesarrily.  sw2 and sw4 would be my choice.  That said a true mesh will always be the surest method where available.
