This can be done by providing the given or ID on the Wallet top-level query's identity input and the user(s) in the socialFollowers:

Try Demo

Show me if fc_fname:ipeciura.eth is a follower of a group of users on Farcaster

Code

query isFollowing {
  Wallet(input: {identity: "fc_fname:ipeciura.eth", blockchain: ethereum}) {
    socialFollowers( # Check if fc_fname:ipeciura.eth is a follower of these user identities on Lens
      input: {filter: {identity: {_in: ["0xeaf55242a90bb3289dB8184772b0B98562053559", "betashop.eth", "yosephks.cb.id", "lens/@deepesh", "lens_id:100275", "fc_fname:dawufi", "fc_fid:602"]}, dappName: {_eq: farcaster}}}
    ) {
      Follower {
        dappName
        dappSlug
        followingProfileId
        followerProfileId
        followingAddress {
          addresses
          socials {
            dappName
            profileName
          }
          domains {
            name
          }
        }
      }
    }
