but the 1st point about gifts from relatives of members of HUF, not sure about it, its debatable.

Gifts from members of HUF are not taxable and hence gift from karta is not taxable.

HUF can get its initial contribution from members and their relatives without inviting tax liability. However, members contributing to HUF beware, income derived from member contribution is liable to be clubbed in the INDIVIDUAL's income. 

About how can an HUF earn money, you can start a business in the name of HUF, a property belonging to the HUF can be rented out, etc.

Do not gift it. Show it as a loan. If karta has availed loan, then charge loan to HUF also. else interest free is OK.
