all switches and pc can ping each other
however, when using a router to do inter vlan routing with SVI
in packet tracer 7.0 can not ping 192.168.5.254 which is ip address of router from switches
is the model of switches or router wrong?

Hi
Are you trying to ping 192.168.5.254 from PC or from switch?
Anyway, I guess you have this problem becouse you have gateway's IPs in another subnet, than switches. All your vlans terminates on the switch3, so for switch2, switch1 and both PC switch3 should be gateway, then you will be able to ping 192.168.5.254. But if you need to reach network beyond the router, you have to use dynamic routing.
For switch1 it should be
ip default-gateway 192.168.2.3
For switch2
ip default-gateway 192.168.3.3
If you want router to proceed intervlan routing you have to terminate all vlans on the router. To do this you have to configure a subinterface for each vlan.
For example:
interface GigabitEthernet0/1.2
encapsulation dot1q 2
ip address 192.168.2.1 255.255.255.0
interface GigabitEthernet0/1.3
encapsulation dot1q 3
ip address 192.168.3.1 255.255.255.0
interface GigabitEthernet0/1.5
encapsulation dot1q 5
ip address 192.168.5.1 255.255.255.0
For switch1
ip default-gateway 192.168.2.1
For switch2
ip default-gateway 192.168.3.1
For switch3
ip default-gateway 192.168.5.1

A. after tried router on a stick, the switch 1 from vlan 2 can not ping 192.168.3.50 which is the PC in vlan 3
i see that router can ping both vlan 2 and vlan 3 pc 192.168.2.50 and 192.168.3.50
switch 1 can ping 192.168.3.3 and 192.168.3.254, but can not ping the PC
B. why this case can only use router on a stick but can not use SVI based intervlan routing
C. if using another group of vlan, should we use second cable to group vlan?
that means vlan 2 and vlan 3 using gi0/0, if another group is vlan 10, and vlan 11 , then need extra cable to use gi0/1 ?
