All my servers have 2 network cards on network card is connected to top switch and one network card I connect to bottom witch.
I also need to have 10 different vlans on switch.
I need to configure switch for failover redundancy please give me step by step configs how I can do this say when on path to switch from server fails so the spare path will take over.

In a stack environment, it's not a situation where one switch is active and the other is standby.  Both are active.  If you're dual-connected to a stack on two different switches, and one switch goes away, the other switch is still active and you'll still have connectivity.  What I'm not certain about is the mechanism, not sure if it's an Etherchannel mechanism or if spanning tree is involved.

HSRP in what respect? That's usually for routers not switches.

A Cisco switch stack for all intents and purposes acts as if it is a single switch. One will be a master of the stack and another will take over if that fails but that is completely transparent to the client hosts.

Just connect two stacking cables between them (for redundancy) and you set it up so they have a common configuration, for all intents and purposes they are a single switch with different Chassis numbers on the interfaces. Eg. Fa1/0/1 on the first switch and Fa2/0/1 on the second switch.
