Is it possible to write an Irule for SSL exception based on IP address?

Something like this?

when HTTP_REQUEST {
    if { [IP::addr [IP::client_addr] ne 10.55.22.22] } {
        HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri]
    } else {
        pool http_pool
    }
}

Add this to the virtual server listening on port 80 and replace http_pool with the name of the pool you want to use.

Can i use below irule to disable http to https redirection for VIP on port 80??

when HTTP_REQUEST {
    if { [IP::addr [IP::client_addr] eq 10.55.22.22] }
    {
      return
       do nothing
    }
    else {
    HTTP::redirect https://[HTTP::host][HTTP::uri] }
    }

Question 1:

Yes, by doing something like this:

when HTTP_REQUEST {
    if { [IP::addr [IP::client_addr] ne 10.55.22.22] or [IP::addr [IP::client_addr] ne 10.55.22.23] } {
        HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri]
    } else {
        pool http_pool
    }
}

Note that data group lists are recommended if the list of IP's grows longer.

Question 2:

Yes.
