Can we stack WS-C3750G-24PS-S with WS-C3750G-48PS-S with the same IOS version?
Also how many switches we can stack in one master switch?
Cisco StackWise technology unites up to nine individual switches into a single logical unit, using special stack-interconnect cables and stacking software. The individual switches can be any combination of Cisco Catalyst 3750 and Cisco Catalyst 3750-E Series Switches. The stack behaves as a single switching unit that is managed by a master switch, elected from one of the member switches. The master switch automatically creates and updates all the switching and optional routing tables. A working stack can accept new members or delete old ones without service interruption.

You can. Make sure both switches have the same IOS and the same Feature Set (example IP Base). Before you stack the two together, power down the switch member, connect the stacking cables then power up the switch member. Failure to do so will cause BOTH switch to reboot.
Maximum switches in a stack is 9 (including the master) but I personally wouldn't recommend more than 7 (including the master).
