8 is invalid, it is an interface implementation, unused parameter is required
5+6+7 should be one issue
4 is level 2: Med Risk issue! a good spot (something we also spotted/have resolved since)
no. 4 is a duplicate of #103, a more severe issue, but I won't upgrade it because the impact is not detailed in any way.
Although, I'll give you kudos for some of these findings. great work!
unused local variable PortalFacet.repayAavePortal() -
adopted
variable in https://github.com/code-423n4/2022-06-connext/blob/main/contracts/contracts/core/connext/facets/PortalFacet.sol#L98Unused function parameter PortalFacet.repayAavePortalFor() -
_router

The router must be approved for portal and with enough liquidity, and must be the caller of this function
.However a require check is missing to ensure msg.sender is the router - https://github.com/code-423n4/2022-06-connext/blob/main/contracts/contracts/core/connext/facets/PortalFacet.sol#L80_local
