HD wallets support multi coins.

does it mean HD wallets support multi networks? like omni for bitcoin, TRc20 for tron?
what is network role in the HD wallets? I think in the derivation of child for multi coin, nothing, yes? but what about in sign a transaction? is there any difference or all networks are same?

No.

A Bitcoin wallet can implement BIP-0044 without supporting any cryptocurrency other than Bitcoin.
