I am not sure that I understand what you need. Can you, please, provide topology?

However, on drawing you have in network down ip addresses from 192.168.90.X/X assigned to hosts I guess those should not be down :). Also address on router is 192.168.0.201 and hosts are 192.168.207.x/x I guess it is typo (check you design and adjust IP addresses).
If those are not typo I guess you created router on the stick and then passive interfaces for EIGRP should be all subinterfaces to local network and rest of the networks should be added to EIGRP so those too can be advertised.
I assumed everywhere fa0/1 was used as interface to local network (you should adapt it to your design).
It is easy to check what interface should be passive (the one with private IP address on it (that should be configured with network statement)):

Wrong network and passive interface (you have wrong passive interface on router 1 and 2). According to configurations passive interfaces everywhere should be fa0/0.
On router 3 network should be 192.168.271.0
But you can remove passive interface command for practice, it is security mechanism. passive interface should match with interface to hosts, not to EIGRP neighbors. If interface is passive hello messages will not be sent from that interface and routers can't establish neighbor relationships on those interfaces.

Serial0/0/0 90.90.90.2 YES manual up downYour serial interface protocol is down. Problem is not related to EIGRP, but for serial interface.
You can try cable serial DCE cable instead of serial DTE that you are using.
Since for serial links one side must be DCE, if both sides are DTE protocol will be down.
But I am not sure what is solution for Packet tracer.

That's how EIGRP works.
:)
Serial link is way much slower than Fast Ethernet link.
By default you can load balance traffic only through 4 equal cost paths.
If routes are not equal cost routes, by default only best route will be placed in routing table.

Ok got it sir, but there is a problem actually we have 2 different ISP link in my network which is connected to a single router with different location. in my network there is 100 + computer out of which 50 in connected with 1 ISP router & rest of connected with 2 ISP router. What happens now is if my 1st ISP goes down my all 50 user stuck in same case we run batch file for using 2nd ISP & all 100 user will be connect with 2nd router.
In that scenario if my 1st ISP or 2nd ISP goes down, i am not able to find out which one is down because it will connect computers automatically for running ISP router.
I would like automatically fail over should stop.

EIGRP knows that both neighbors exists and what networks are advertised by each of them. Router will have to rediscover the best path, no problem there. EIGRP can be configured to use unequal load balancing if you want to do so (but it can create new challenges).
router eigrp 1
variance x
However for failover scenario, have in mind that if one of the links is down you can run into problem with NAT.

Ok got it sir,
Thank You so much.
Thank You so much.
You can shut Fa 0/1 interface on R2 or R3 and see that is traffic rerouted.
You are welcome.

Sir,
There is a issue is my serial link goes down in same time eth link getting RTO 5-6 time because of which user disconnect which is connected with eth link. what is the way to serial traffic in & out via serial link only & eth traffic in out via eth link only ?

Not sure what are you trying to describe.
Real world or lab situation?
Real world or lab situation?
I tried it in packet tracer and the same happened what you described. That is some packet tracer bug. That's should not happen in real world, I expect other problems in the real world.
