Hi I have a few Arum Lilly plants in pots on my balcony. This year I'm having a huge problem as the two flowers that did emerge didn't even open and just died on the stalk. Just about all of the leaves are slowly dying - turning brown from the edges. I've been removing all of those as they started but I'm left with only a couple of leaves. Even the unopened leaves show signs of dying on the tips. I don't see any sign of insect infestation. What could it be?
There are a few causes for this, but usually it is due to lack of phosphorus and potassium, or too much nitrogen.
Other causes can include low humidity, low temperature, and dry soils.

When I first moved into this house, there was a single plant but now that other plants have been added and regular weeding, the dragon arum lily plants have multiplied to the extent they are a pest and need to be eradicated. I would like advice on how this can be done, thank you
A bit of research tells me you have a problem on your hands. Apparently the only solution that is known at this time is the use of powerful weed killers, and even that doesn't sound encouraging. Visit your local nursery and see what the latest thinking is on this invasive plant. Here's a link to a Washington state extension service article about eradicating arum:

Hi, I have been told if you plant different hybrids with common white one all the lilies will then return back too white, is this true as I have an apricot/red?
Your original plants should not revert back, but if they reseed the seedlings probably will not look like the original plant. Also if they cross with another you may get something different.

Many Arums are incredibly invasive, unfortunately. Chemical means are almost never useful. There are a few ways to kill them, but most take years to kill.
There is one way that will work, fairly, quickly. It will require several days of pouring boiling water on each patch of them. Do this once per day for about a week, and it will kill most, if not all of them.
Here are some articles that will help:
