My alocasia houseplant does not get new leaves. Existing leaves one by one turn brown on edges and then total leaf does. What to do?

Get a different kind of plant.

My experience with alocasia's of this type has been less than desirable. They love heat, humidity and light...things I have trouble providing year-around.
There was not any info about fertilizing in the care section.
Alocasia can benefit from a fertilizer applied every 2 months during the growing season.
Use a fertilizer that is formulated for foliage plants and apply as directed on the package.
I germinated many, many alocacias from seed. They germinated quickly, and most now have 2 leaves. I did them in a tray. I have tried repotting now into bags, but most of those I moved have died. How should I handle the seedlings at this stage?
Allow them to get larger before attempting to repot.
Then follow planting information in the link below.

I had an accident today in which my entire plant stand fell over on me, including all my plants, knick-knacks, and photos. My African Mask plant, which I've had for a couple of months now and is doing great, fell over head-first. Some of the bigger stalks are bent, to the point where they won't stand alone without support. I've got them tied upright for now. Will these damaged stalks be okay? Will I have to eventually remove them? Thanks for any assistance you can provide.
I would continue to just support the leaves and plant structure.
Your plant will likely correct itself over a bit of time.
Alocasia will die down and go dormant at some time, so you plant can have a fresh start again.
Here is a link to refresh you on the care requirements.

How do you propagate alocasia?
Propagation is from dividing the rhizomes in spring.

This could be a number of pests.
Try treating with Neem Oil.

Will they affect drains from the house?
I have found no reports of damage to drain lines or foundations from Elephant Ear plant.
