Hello,

1-I can see the issue. We are checking it now and will come back with a custom code for you to use. Also we will update this in the next theme update.

2-The logo in mobile is centered to it’s section (middle column). To move it right/left even more, please add this code into Customize > General > Custom Codes:

@media (max-width: 991px){
.header-row .header-row-inner .c-middle {
    padding-right: 45px !important;
}
}

Change the value to your wish.

3-Yes, add this code inside the @media (max-width: 991px){ block above:

.header_container.cl-header-sticky-ready {
    background-color: #00491a;
    position: fixed !important;
    z-index: 5000000000 !important;
    width: 100%;
}

Best regards!
