Hello,
Assuming You talk about MX series, then

1- Can we apply the ingress policy on Multiple 100GE interfaces?
I believe You mean FW filter with "then port-mirror" action, and not a JUNOS policy statement - then yes,
You can. Beware that Your port-mirror output interface BW must be enough to send all mirrored traffic out.

3- Is it mandatory to configure destination IP address for SPAN packet receiver?
The short answer is yes , for L3/IP mirroring, and no for L2 mirroring.
The long answer is if You mean "next-hop 10.10.6.1" in this example https://kb.juniper.net/InfoCenter/index?page=content&id=KB33488
then this is NOT a "destination IP address", the mirrored packet' dst.IP in the original IP header is not overwritten.
It is a nexthop IP and You also need a static IP entry for it - unfortunately, the static ARP bit is missing from this KB.
This nexthop IP is not required for L2 mirroring https://www.juniper.net/documentation/en_US/junos/topics/example/layer-2-services-port-mirroring-firewall-filter-logical-interface-example.html
