How do I set up multiple VLANs on a single switch?
I have two 3750G-24PS switches and three unmanaged switches. I have configured VLANs (15 nos.) in 3750. Is it possible for me to use those three switches for all VLANs or do I have to use separate switches for each VLAN?

You can have as many as 1024 VLANs on a single switch and you need not create the same on all switches. Create a VTP domain and specify one switch as server and others as transparent. All the VLANs created on server switch will get replicated to other switches.
