The leaves are nice and healthy, but the bulbs are slimy and this week they are full of maggots. Can I save the green part and burn the bulbs or is it to risky for my family’s health.
Although, not preferable, the maggots themselves can be considered edible. (Gross)
If the tops look good, then there will be no harm in eating them. There would be little to no harm eating the rotting bulb, but I can't imagine that it would taste anywhere near "good".
The tops should taste just fine, though.

I'd like to let my onions get bigger, but we've had some torrential rainstorms and a hailstorm. They have caused the green part of the onion to fall over.
After they die off for the year, they should only be left for a week or two. You can leave them longer, but they could either rot, or start growing again. If it does start growing again, there is no harm in killing the growth, and eating the onion. Once it flowers, though, it may not be worth eating. This happens, usually, during the second year.

This is the first fall I am trying Walking Onions and have some bulbs coming this fall, to be planted in raised beds and am wondering if I will need straw, mulch or other protection for these beds in the winter?
No, these are hardy all the way to zone 3! They will consider your winters quite warm compared to what they can survive.

I live in Malta and do not have a garden. I have a lot of plants in pots that live on my terrace. I have been pulling the weeds out 2-3 times a year and snipping off the flowers which come in spring to avoid the millions of tiny seeds spreading. However as the tiny bulbs have wound themselves around the roots of the plants I can never entirely get rid of them and pulling them up only stops them until the bulbs I can't get at grow again fairly quickly. Have you ant advice on how to deal with them more effectively, please?
If they are wound around your desired plants then the only thing to do is to dig out your desired plants and rinse off all the soil (and bulblets of the onion plants) and replant in new soil. Check weekly for new weeds and pull them up right away before they get hold.
Onion growing in Zambia, Mpika in particular, is becoming a problem.

IRRIGATION
Research shows that drip irrigation might be the best method for growing onions. They need regular, deep watering for best results.
