Suppose our organization has been assigned a class /24 subnet 216.21.5.0. Then we subnetted that and used 255.255.255.224 as our new subnet mask, so the network ranges are 216.21.5.0-216.21.5.31, 216.21.5.32-216.21.5.63, .64 -.95 and so on. Would a PC in 216.21.5.0 -216.21.5.31 be able to ping a PC in a different subnetwork eg:216.21.5.64 -216.21.5.95 without using a router?
And can this be done using VLANs?

No and No. Moving packets between IP networks (which you created by subnetting) is done by a router.
A netmask and ipaddress determines what other addresses can be contacted directly on an interface. If you want all your machines to communicate without going through a router then use a netmask that covers the whole IP address range and skip subnetting.

you can even ping two hosts in a different VLAN with out a router provided both hosts should share same network ID.
This can be achieved by playing with NATIVE VLAN.

VLANs partition switches, i.e. limiting the ports on which broadcast traffic is flooded or visible. You still need a router or something that can route "in between" VLANs. It's possible some "Layer 2 router" devices may have this feature. It would be a feature specific to your router. – LawrenceC – 2012-08-18T17:17:14.903
